Hey TropicalBob,
interesting post, but I'm not sure I 100% agree with everything you say.
First up is the public perception issue - Sure, some might think it looks a bit silly, but IMO a large and increasing proportion of the public also sees smoking as looking, well if not silly then damned unattractive. My experience so far has had people intrigued and most smokers seem pretty happy/excited about it - since on the surface it appears the perfect way to continue the habit and not suffer the ill-effects.
I can honestly say that no-one has yet said it looks silly, or even that it is "pretend - smoking", most are pretty sophisticated in their understanding of the nature of nicotine addiction.
You are absolutely right that pipes and cigarettes are superior. But that is at the moment. You know how quickly technology develops, and pretty soon they will get it pretty much identical in sensation. In China, a huge number of people have adopted the e-cigarette, so consumer demand will drive forward changes in the technology.
The actual e-cigs will get smaller and lighter and hopefully take on their own identity, not trying to replicate a cigarette (the LED has to go!).
I don't know how long you've been e-smoking, but most long-term e-smokers seem to have had at least one e-cig give up on them. The suppliers are by and large more than happy to replace them at no-charge, knowing full well that the internet is a pretty good place to have your reputation destroyed. Although I do agree that being without your nicotine fix will send you back to the ciggies quicker than anything.
Still, it is all about individual taste!
