as for what type of pv will be the most prevelant when all these changes do take place, i disagree again, i think it will be stick style batt's like are currently available in 7/11's and gas stations and what not, although obviously of better quality. think the smokelessimage volt. people don't like the look of eGo's until they actually get over the fact that vaping isn't smoking. cig sized pv's are where the bulk of the money is at, that's where newb's will spend the most, and it's where MOST people will spend their time vaping, not everyone turns vaping into a hobby, some people do just use it to get off smokes or for social reasons.
those of us that get in to mods, and provari's and all that **** do it for the same reasons that people "mod" their cars. but for 99% of the population, a car is just a vehicle to get from point a to point b. same thing with ecigs, in the majority's eyes, it's just there to get people off of smokes, doesn't have to be fancy.
