Agree about the funny looks. I was on the 1 train last weekend, and someone took an e-cigarette out of her purse and started smoking. My first thought was, "OMG this is so illegal, I can't believe someone could think it's OK to light up on the train!" Then I realized it was an e-cigarette.
I imagine e-cigarette smokers must get this stunned reaction quite frequently.
Friend of mine switched to e-cigs a while back to try and quit. She seems to be doing pretty well. I met her at an airport terminal just before a transatlantic flight and she was complaining that the airlines don't let you use e-cigs on the plane.
I did double take when I saw her e-smoking in the terminal though. ;)
