Enfield,
I think you're really on to something here. Thus far, vaping has been aimed at analog cigarette smokers (which used to include me).
However, I (and, I think I'm not alone in this) am enjoying vaping far beyond fulfilling nicotine craving. In fact, most of the time I vape 0 nicotine levels. Sucking on a stick, inhaling flavor and blowing out "smoke" is immensely satisfying.
And, without working at it, my snacking has dropped off considerably. I'm eating more for nourishment and to satisfy hunger ... and to indulge in flavors not yet available in e-cigs, e.g., steak, pizza, bacon & eggs, ham & cheese, shrimp scampi, etc., etc.
Even beyond weight loss, I see great potential for the PV as a ... pleasure device. And, yes, "PV" rather than e-cig, in this context.
If you don't mind, I'd like to begin a thread in the General E-Smoking Discussion subforum (acknowledging and linking back to your post here).

Smokefree and vaping for all of 12 days now ... haven't saved any money yet
