I'm not going to pass judgement on who's wrong and who's right, we're all welcome to our opinions as you say, but i'd suggest that it's worth ignoring any opinions that resort to name calling/belittling others intelligence based on their opinions.
We're creatures of habit, part of the addiction of smoking is the feel of a ciggerette in your hands and the inhaling of smoke, by passing that off to a device that is healthier than ciggerettes we're only moving the addiction to a safer alternative. So id' say you're both right and wrong at the same time about people getting addicted to e-cigs...they're already addicted to the habit of holding, inhaling etc. but that habit being moved to a safer alternative can only be a good thing

breaking the addiction of habit is one of the hardest bits i've found about quitting. I can drop the nicotine reliance quite easily, but i still want to hold something.
