The newest one! LOL! Seriously, the e-cig PV (personal vaporizer). Still transitioning over, but I find it very similar to an analog when used properly. Lots of flavors of juice to choose from and the second hand steam is sweet and clean smelling. This is particularly nice since flavored cigarettes were banned. Also, there's no 'smoke', I can use it in the house, the car, at work, etc. One should even be able to use it on an airplane if you can get it through the Trinket Stealers of America.
