There are still studies being done on whether there are long-term side effects from vaping.  The vast majority of what you are going to find in relation to any side effects are all considered anecdotal by scientific standards.  From personal experience, the only side effects I have experienced are: easier time breathing, lack of craving analogs, healthy weight loss (because I can exercise without running out of breath), and I smell better.  Those are just a few of the longer-term side effects I have experienced from vaping.  There were some short-term side effects when I first started, such as coughing when I inhaled vapor.  But it's a different substance than cigarette smoke and what ex-smoker didn't cough the first few times they inhaled cigarette smoke?
As far as Juul, I don't know enough about the product to give an opinion.  However, I wouldn't say it's any better or any worse than anything I use.  In my opinion, it is one option among many to help a person quick smoking.
Personal disclaimer - I DON'T recommend vaping if you never smoked.  I think it should be used as a tool to quit or cut back on nicotine use from traditional tobacco, not as a way to get nicotine if you never used traditional tobacco.

I'll try to answer as best as I can and my answers/recommendations are based on United States information.
The only mac compatible software for updating firmware that comes to mind is eScribe, which is used for updating the firmware on DNA chipsets.  Something comparable (actually much better, in my opinion) to the smok alien 220w you have been using is any mod using a DNA 250 chip.  
As far as your specific requirements:
escribe (Currently with US and International versions for mac, but again, for DNA chipsets only) Maybe not under $100, but you can find the Lost Vape Triade DNA250C for about $120.  It can't jumpstart a car, operate a spaceship or function as a PS4 controller, but it is an excellent mod. Since it's just a mod, you can use just about any tank you can get your hands on. It uses 3x18650 rechargeable batteries. The Triade is solidly built.  Mine is going on 3 years old and I've never had an issue with it so I've never had to take it apart.  That being said, it does appear to be fairly easy to disassemble/reassemble.

I don't personally vape tobacco flavors, so I can't make recommendations on any tobacco flavors.  I can, however, make recommendations on how you can go about finding the flavor that is right for you.  
Everything in the vaping world is subjective - especially when it comes to e-liquid.  I find it much easier to find a person who likes the same setup (mod, tank and coil) as me than I do a person who likes the same flavors as me.  Everybody's taste buds are different and everybody is going to like different flavors.  To borrow an analogy from another member here on VT, what may taste out of this world to me could very well taste like wet socks to you.
One to my recommendation: make a visit to a B&M (or multiple B&M's).  I have visited a lot of B&M's specifically for the purpose of trying new flavors.  A good B&M (and no, they aren't all good) will have employees who are intimately familiar with each line of liquid they carry.  They may not know how it tastes, but they should know how well it sells and that should be an indication of whether or not a particular flavor is worth trying.  They should also know specifically which tobacco flavors they sell so they can help you with trying tobacco flavors specifically rather than you spending you time looking at their "menu".  Visiting a B&M to try different liquids doesn't obligate you to purchase from them.  That is entirely up to you.  Unless the liquids they are selling are "house blends" (made specifically by them), chances are you will find it cheaper somewhere online.
Last recommendation - Keep an open mind when trying e-liquids.  You may surprise yourself and find something non-tobacco flavored you like.  

I found a Eleaf Lemo 2. and an Lemo drop.  Which one do you think would be closer?

Little late to the game, but not too late.
Might I suggest a Lemo 1 (if you can find one)?  This is an awesome, and in my opinion highly underrated, MTL RTA.  Single coil deck that is really easy to build on.  It's kind of a PITA to fill, (a needlepoint bottle is virtually a must), but with MTL you aren't burning through as much liquid.  This was actually the second tank I ever bought and I still keep it in regular rotation.  I should have hit up one of the local stores during their "going out of business" sale...they had about a dozen marked down to $5 a pop.

I just received a Templar AIO kit by Vapor Talk in the mail yesterday.  Since setting it up I have been vaping on it exclusively.  Here are my first impressions.
Packaging: Very nice box art.  It is definitely representative of the Vapor Talk brand.  If I hadn’t already seen photos of the device I would have been tearing into the box in anticipation of checking out the contents.  Instead, I tore into the box in anticipation of actually getting my hands on what was inside.
The contents:  It’s no frills.  You get the mod, 2 coils, the standard USB charging cable and a manual that is easier to understand than most I have seen.
The mod: Very simple to set up and operate.  The hinged cover for the charging port (located on the bottom of the device) easily swings out of the way and has a magnet to keep it in place when the cover is in the ‘closed’ position.  The top comes off easily, even with the child proof design.  I had no trouble screwing a coil on and filling the reservoir/tank couldn’t have been simpler.  The appearance is sleek, fits well in my hand and appears to be constructed well.
There do appear to be a couple of minor differences and/or omissions between the manual and the device.  The manual says the charging light will flash 4 times to indicate a successful connection.  I connected the device to 6 different ports with two different charging cables and each time I got a solid red light.  This was after the initial “charging” because the fact the light didn’t flash 4 times was actually brought to my attention after the fact.  The device also must have been mostly charged because the charging light went from red to green in a matter of minutes.
The other omission I noticed from the manual is the battery mAh rating.  It isn’t listed in the manual but is listed on the VT website – 1000 mAh.
Operation: Charge it, 5 clicks to turn on, press the fire button, inhale and enjoy.  It doesn’t get much simpler than that. 
Experience: Overall it will serve as a very capable backup for me.  I have been using it exclusively for close to 24 hours as of this writing and other than the fact that I might need to step up the nicotine it has served its purpose.  I normally vape 3mg between .1 and .2 ohms, so going to .5 ohm just isn’t giving me the same “hit” I’m used to. 
I have done everything from short 1-2 second drags to longer 8-10 second drags.  Casual hits every few minutes to chain vaping.  The tank does get warm when chain vaping.
I will admit that I was actually hoping it would serve as a nice little stealth vaping device, but with .5 ohm coils and the way I do DTL hits, that just isn’t going to happen for me.  It might be a little stealthier if I up my PG, as the juice I have in it right now is a 10/90 PG/VG ratio, but even if I switch to a 50/50 or even a 60/40 I think I’m going to be producing quite a bit of vapor simply based on the way I vape.
The airflow does not appear to be adjustable.  That’s fine and doesn’t take away from the operation of the device; it’s just tighter than my personal preference.
Appears to vaporize the liquid and utilize the battery very efficiently.  I am still on the original 2ml of liquid I put in the tank, though I’m definitely getting toward the bottom end of that.  By comparison, I would have easily gone through 6-9ml of liquid with one of my normal setups with the amount of vaping I have done and I would have easily drained 2 2500 mAh batteries, though I have no idea how close to drained the battery is.  At 1000 mAh I would have though I'd have had to charge it a couple of times by now, but I'm still on the original charge.
 
 
 
 

A little late to chime in on this, but... 
In regards to TFV8 tanks, coils and SS: The tanks are SS.  The coil housings are SS.  The coils themselves are Kanthal. 
In regards to using TC with Kanthal, the Hohm Wrecker Gen 2 and the Hohm Slice can do TC with Kanthal with their proprietary chip.  Not sure about the Hohm Wrecker Gen 1.  I've been using a Hohm Slice since December and run it almost exclusively in TC with Kanthal coils.  So far these are the only two (possibly three) mods I know of that will run Kanthal in TC.

Short answer: No, don't assume that.
The following is purely based on my experience.  When a manufacturer uses something other than kanthal for the coils they provide in a kit, they generally specify what type of metal those coils are made of.  When it comes to the TFV12, SMOKTech mentions "Stainless Steel".  That is for the actual tank construction, not the coils.
I haven't pulled the trigger on a TFV12 yet, so I don't know if there is something in the (most likely poorly written) user manual that specifies the coil material.  In this scenario I would err on the side of caution and make the assumption the coils are kanthal.  I could be wrong, but I have yet to see anything anywhere on the internet to prove me otherwise.
Your best bet...use power mode with those coils, not temp control mode.  When you are 100% sure of the material, then use temp control.

Most people don't use SS 304 (food grade SS) for coils, but most do use SS 316L (surgical grade SS). 316L has a lower carbon content, and is more resistant to corrosion than 304. 
Most of the tanks manufactured do use SS 304 to make the main body of the tank, I believe most of the drop in, and premade SS coils are made with 316L wire.

It looks like you are using TCR mode of your gx350 (I'm assuming there is a TCR setting where you can dial in the specific setting for a specific type of wire) and that looks like the temp co-efficient for SS304 wire.  If you are using SS304, then yes, that setting is good.  If you aren't using SS304 then I can't recommend the proper setting. 
Your best bet would be to use the basic setting for whatever type of wire you are using (Ni for nickel, Ti for Titanium or SS for stainless steel).  If it's kanthal, don't try to use it in TC mode.

I'm currently on night shift.  I have some time on my hands tonight and I needed something to keep my mind occupied in order to stay awake.  This article and the study it cites were a good way to do just that.  As a result of the digging I did, I'm going to go against the grain and play "Devil's Advocate" where this article is concerned.  It is shoddy and misleading journalism, at best.
The very first sentence of the article was inaccurate: "A recent study published in the journal of Environmental and Molecular Mutagenesis revealed that e-cigarettes do not cause cancer, unlike tobacco." 
No, it didn't reveal that.  What the study revealed is that the nicotine contained in the aerosols from e-cigarettes did not appear to promote growth in tumor cells.  I could have told you that without conducting the study.  In fact, any number of people around here could have come to the same conclusion.  It has been widely known for a very long time that nicotine is not a cancer causing agent. Therefore logic tells us that nicotine will not promote growth in cancer cells.
From the study: Results from this study suggest that e-cigarettes may have reduced tumor promoter activity compared to conventional cigarettes and therefore may provide a safer alternative to cigarettes.
Suggest.  May have reduced.  May provide.  The authors/researchers were very careful not to state anything along the lines of "e-cigarettes do not cause cancer".
However; the purpose of the study wasn't to determine that the nicotine in e-cigs doesn't cause cancer, as the author apparently wants us to believe.  The actual purpose of the study was to essentially determine the usefulness of the Bhas 42 assay in further studies.  Essentially, this was a study of a study method.
Toward the end of article the author points out the FDA continues to warn about potential health risks from e-cigs.  That's true.  The FDA does warn about potential health risks.  Yet the author's own title of the article: VAPING found to be vastly safer than smoking cigarettes, yet the FDA ridiculously claims they pose identical risks to health - is grossly inaccurate and misleading.  No, the FDA does NOT claim e-cigarettes pose the identical risks posed by cigarettes.  They FDA warns (as opposed to claims) of potential health risks (as opposed to known health risks) and they openly state their concern that some of the products may contain ingredients that are toxic.  That's actually true.  Some of the ingredients found in some liquids are toxic in high enough doses.  Even water is toxic in high enough doses. 
While the FDA, in my opinion, has way over-stepped their boundaries where the deeming regulations are concerned, they are very careful not to make the claims the author asserts they make.  Yes, there needs to be some oversight.  No, that oversight should not include hardware.  That oversight should be limited to the actual items that contain the potentially - POTENTIALLY - toxic ingredients.
Sorry for my rant.  Just getting a little tired of seeing so many articles by "journalists" that either say the same thing over and over or, as is the case with this particular article, don't provide accurate details.  Do they not understand that the inaccuracies will actually do more harm than good?  Hopefully some legal beagle out there realizes that and is smart enough to separate the treasure (good articles) from the trash.

Excellent review! (I'll be gather up any reviews that pop up on the forum and sending them along to the team) We spent quite a bit of time on this device as AIO's are becoming popular. It's especially important as TPD sets in place over in Europe. 
I agree, the LED fiasco needs to be fixed. Luckily, this should easily be addressed. During testing we were able to adjust the device via the USB port. The software is not user friendly but I'll bring up the possibility of a potential firmware update.

I used a small pair of vise grips with the curved jaws before..just make sure not to overtighten them and be sure they lock on the base, not the air control ring...worked great! Good luck

Se stai solo cercando il tubo vero e proprio allora consiglio il Dotmod Petri Lite. Non sono completamente sicuro del tasso di cambio tra l'euro e la sterlina britannica o dollaro americano, ma se Google fosse corretto, dovresti essere in grado di ottenere uno di questi per circa 120€.

The OP was asking about recommendations for a good quality mech mod for about 120 euros.
I recommended the Dotmod Petri Lite.

@theclaw20

Instant message me and let me know specifically what wire gauges you're interested in. I typically get my wire in 100' spools for 20-28g and 1000' spools for 30g and smaller. If I have it I'm willing to part with some.

Sent from my heart using the Vapor Talk App. OK...OK...I'm kidding. I have no heart. But I did use the Vapor Talk Mobile App.

In a nutshell, yes, I'm concerned about the long-term effects of vaping.  And in a nutshell, I would rather be inhaling 4 or 5 or 6 vaporized liquids/chemicals with relatively unknown effects that are FDA approved than inhaling 7000+ carcinogens that are KNOWN to have adverse effects on health (and are also FDA approved, by the way).  
I'm curious about where you got your information about the toxicity of PG, thoughh.  There are several old and inaccurate studies still floating around (and still being cited as 'gospel' by the fear mongering media) concerning PG.  The conditions used during those studies were unrealistic.

I'm taking the survey now.  Funny thing about all the pictures...none of them has created an craving, urge, desire or need to vape, but some of them have caused a craving for red vines, created an urge to use a pencil to write this response by hand and an inexplicable desire to pick my nose.

I read this in a blog called Vaping Post this morning. Thought it quite interesting seeing that it was done in the good ole USA. (I wanted to copy/paste the link and my computer wouldn't cooperate.)
Air Sampling confirms secondhand vapor is harmless
Results obtained from an air sample of a small non-ventilated vape shop, clearly indicate that the amount of toxic substances present in the air where a lot of vaping is taking place, are of insignificant levels.
The California Department of Public Health has been carrying out air sampling in vape shops throughout the state, as part of its initiative to determine the health effects of second-hand vapor exposure.
Earlier today in his blog, Public Health Expert Dr. Michael Siegel pointed out that the results for this report were obtained from a relatively small and non-ventilated vape shop, where many of the employees and 13 customers were actively vaping while the sampling was taking place, hence what would be considered a situation presenting a high level of exposure to second-hand vapor. However, given all these unfavourable conditions, the results still reported no dangerous levels of exposure to any hazardous chemicals.
The main results of the air sampling go as follows :
Nicotine: Not detected Glycidol: Not detected Formaldehyde: 7.2 ppb Diacetyl: Not detected using standard method 2,3-Pentanedione: Not detected using standard method Acetyl butyryl: Not detected using standard method Acetoin: Not detected using standard method Acetone: Not detected Ethyl benzene: Not detected m,p-Xylene: Not detected o-Xylene: Not detected Toluene: Not detected Acetaldehyde: Not detected Acetonitrile: Not detected alpha-pinene: Not detected Benzene: Not detected Chloroform: Not detected d-Limonene: Not detected Methylene chloride: Not detected Methyl methacrylate: Not detected n-Hexane: Not detected Styrene: Not detected Finally putting fears about formaldehyde to rest?
Dr. Siegel pointed out that the level of formaldehyde detected, is consistent with the levels normally found in indoor and outdoor air levels under baseline conditions, adding that the only other chemicals detected were ethanol (alcohol) and isopropyl alcohol. “This study, although conducted under very high exposure conditions in a small, non-ventilated vape shop with many employees and customers vaping and clouds of vapor visible, did not document any dangerous levels of exposure to any hazardous chemical. Nicotine exposure was essentially non-existent. Formaldehyde exposure was no different than in many indoor and outdoor environments at baseline. Acetone, acetoin, other aldehydes, toluene, benzene, and xylene were not detected. Chemicals that have been associated with “popcorn lung” were also not detected by the standard method.” stated Siegel.
No justification for governments to ban vaping
“This study adds to the evidence that under real-life conditions, ‘secondhand vaping’ does not appear to pose any significant health risks.” concluded the public health expert. He added that whilst he himself has been behind many of the smoking bans that took place, based on this current evidence he fails to see a reason as to why governments should ban vaping in public spaces. “With regards to vaping, I just don’t see any reasonable evidence at this time that it poses any significant health hazard to bystanders.”

This article is from way before ecigs were around. I'm not sure if posting a link is allowed and my apologies if they aren't.
Im not bashing ecigs, they helped me quit smoking. I was just oblivious to what PG was and never really researched it.  It's pretty toxic stuff though, but so are cigarettes and the polluted air we are constantly exposed to.  
I don't know of any studies to prove anything indicating the effects but I just wonder I how it couldn't be harmful.  Thanks for your insight...
