Folks!
Don't get so snippy with each other! Face it, you all are your only allies in the world of e-cigs - this divisive stuff is bad news.
I think, unfortunately, as other people have already stated that the batt, atomizer and cart, regardless of nicotine have already been perceived in a certain context by the folks, agencies and organizations that have issues with non-Big-Pharmacy nicotine. As a result, it's moot to try and figure out too late how to separate the issue of nicotine from the issue of the device.
It's sort of like calling 'em PV's rather than e-cigs - too little, too late.
I'm thinking we need to approach the argument as one of "whatever you want to call them - they don't seem to pose a health or comfort risk to anyone NOT using them".
