I agree that it feels different, but the e-cigs have come a long way in the last few years. I tried one a few years ago and did not like it at all, but I bought a few of the newer disposables recently and that's what I started with today. They are much better now and I am hoping that the rechargeable system I ordered surpasses the quality of these. If it does, I think I'll be good to go.
Another benefit for me is that I live in a bad neighborhood in Chicago and constantly have vagrants coming up to me asking for cigarettes when they see me smoking. Since smokes are over $10 a pack in Chicago, that means they also think you have money and some of these people are thieves as well and won't hesitate to rob you if you aren't street smart. The one I ordered doesn't look like a traditional cigarette and I can use it in my apartment, so hopefully I won't be as much of a vagrant magnet anymore.
