LOL, I can't relate Star Wars and Vaping, but I think that soon enough a lot of vaping will be appearing in movies, why not, it's a part of society already.
I don't think people would be upset, why would they? It's something legal, we are not hurting anyone, so it's just a matter of generating awareness regarding vaping and that will only happen with time.
The places that i use them usually don't have many city slickers so i'm cool. When i am in the city around the general public they assume its a normal one. I get tired of telling managers it is not a normal one so i just don't smoke it there.
The looks probably come because they dont notice right away its a E cig. If people just see smoke indoors they might freak out before realizing what it really is.
Well the more fancy the E-cig gets the more people will look, I used to use one that looked like a regular cigarette and never seemed to get anyone paying attention to me. They are so common these days that people who look at you are probably thinking "Oh good, I can walk past him without getting second hand smoke."
I think it just depends on the people you surround yourself with. There's certain people I would feel comfortable vaping around. The same goes the other way around if someone doesn't like smoke, they most likely won't like vape. But it's not like I haven't had times where nonsmokers commented on the smell of my vape :p
