> One thing that really makes a difference is that the vaporized nicotine is actually somewhat hot, like cigarette smoke, when you breathe it in.

Too hot, I found, with the first such device I tried - way hotter than cigarette smoke. With the one I have currently (a bottom coil design, I think it's called, though I'm not into the technical side of the things really) it's pretty accurate.
