If you are happy with the iStick, that's all that counts. A lot of people, experienced vapers, are very happy with their iSticks; they swear by them. I don't care what people use as long as they are able to quite smoking and enjoy the equipment they have. That' the goal here. I just don't think, in my opinion, the iStick is the next ProVari. There will be another new kid on the block shortly that will take everybody by storm yet some will stay with the iStick. It's the beauty of vaping these days; all the different options. Right up until the FDA takes them away from us.
