I've found the evolution interesting as well. I only got in 3 years ago but since then we saw the release of things like the Protank, the rise and fall of the Genesis tanks, the rise and fall of mech mods and in the past year or so the rise and dominance of sub ohm atties with replaceable wicks/coils and variable high watt devices to take advantage of them. Most interesting to is that there has been a shift from small modders to company driven production. When I started, company products were weak and modders dominated. Now the opposite is true and it's for the better for every new vaper. Just as the industry is reaching it's stride, the FDA is mucking it up.
