So I'm one of the sheeple, that's good to know... Vaping i a fairly new thing and the technology advances quickly. That's inevitable. The same thing about the "unnecessary feature present only to sell new equipment" (of course the aim of vape companies is to sell equipment, they'd be pretty lousy businessmen otherwise...) has been said about variable voltage, variable wattage, even reverse battery protection - pretty much every advancement (and it's the same with pretty much every type of technology, from cars to computers). Do you need tc? No. Is it a useful feature? Yes, definitely. Does it make earlier equipment junk? Of course not (and who has said that it does?). Look, if you don't want to use it, fine. But if you dismiss it without really understanding what it does and can do, and put down those that have adopted the technology and find it useful, you kinda come across as a reactionist.
