Personally, I'm going to keep calling them e-cigs. I live in the San Francisco Bay area, and there are many people using similar devices for alternate uses (vaporizing illegal/medicinal non-nicotine substances). Occasionally I run across someone who knows that a "PV" is a personal nicotine vaporizer, but I have absolutely come to believe that we are best off with the association that we have quit smoking those nasty cigarettes with electronic cigarettes. At least until the general public becomes more accustomed to them. I cannot even tell you how many times people have just given my husband and I weird looks when we are vaping on our respective 1300 Spinner w/ a T3 and Provari w/ a Protank. They definitely think we are brazenly using drugs right there in public. When we are using something smaller, people come up and ask, "Hey, are those e-cigarettes? How are they working for you? I/my husband/friend/co-worker/etc, has been thinking about trying them." I am always more than happy to answer questions, give out cards and advice. As much as I would like to see the general public get comfortable with bigger and better PVs, and the term PV itself, I really think at this point in our struggle, we need to give them a term they can understand. Even if it is associated with something as negative as cigarettes.
