Okay, I studied computers for 3 1/2 years, which is actually not that much, so someone with more experience might come along. But the processor is ok, the price to up it is ridiculous and not worth the little extra kick it gives. The video card is AWESOME, my bro has a 512 and runs a few high-quality demanding games like Starcraft 2 at high settings. Black ops should look beautiful. 6 GB memory/RAM is good, don't need any more than that. 750GB hard drive should be enough for whatever you need, unless you got a bunch of *ahem* "freeware" (totally NOT talking about "pirated" movies and/or music <.<). Unless you need it, the other software is for stuff like running a business, or going to college. As for Anti-Virus, I just use AVG Free (like the name says, it's free) and Spybot Search and Destroy (also free), google it if you want.
Battery all depends on how long you need it to run, I just kept mine stationary, so I changed to a desktop. Adaptors are the same, if you need it, get it, otherwise no point. No idea on the difference in screens, probly just a gloss or something...might be worth checking out. "Primary Optical Drive" all depends on what you need, do you NEED Blu-Ray? Do you NEED to burn "ahem" copies of your previously legally bought software? It's up to you.
The networking bit MIGHT be worth $25 to get the Bluetooth, I never used it, but it depends on whether or not you have, or will, need it.
The thing said it had an included port for broadband internet, so if you have dsl or cable internet, you SHOULD be fine, but they have usb adapters for that just in case. If you want some good sound, get a set of speakers, the ones in laptops usually blow. BE SURE to get a surge bar, either use one you have or get a new one, but make sure its good, because you could lose it all in a heartbeat if you have a power fluctuation.
Looks like a good computer, just an fyi though, if you don't need portability, a desktop is cheaper for all of the same components, which means with that money you could get a better desktop
But I digress, hope I helped.
