As a smoker or non smoker would you approve the new mini electronic cigarette?

In my opinion as a non smoker i think are great for all concerned. They are the same length as a traditional cigarette and still give the smoker their necessary nicotine intake. They can smoke it like a real cigarette and exhale smoke, but the smoke is non hazourdous and odour free. It is water vapour! These e cigarettes are non harmful to the smoker and non harmful to those around them. They can be legally 'smoked' anywhere, my realtives smoke these and they don't bother me in the slightest i would much rather more and more smokers tried these and smoke them in pubs, etc rather than them clogging up door ways and fighting my way through the smoke, the smoke that the e cig gives out soon evaporates, leaving no sign of it ever been....... as a non smoker and never have been i think they are fantastic, and for the smoker, you can save loads of money plus they pose no risk to your health and you could still enjoy an e-cig & a pint! If your a smoker or a non smoker, what are your thoughts?
