What i meant was cost is not the only consideration for everyone. To some who can afford it, convenience is more important.
The reason i don't use plug'n'play devices is that i can't get the same quality vape that i get with rebuildables. Right now i spend about $ 40 a month on vaping. If i were to diy exclusively, i'm sure i can bring it down to $ 10 a month or less. I chose not to do so. Likewise if i were able to get the same quality vape with a plug'n'play device for $ 100 a month, i will gladly say goodbye to building, wicking, assembling, re-wicking, disassembling, washing etc .... I'd much rather vape, than maintain my vape.
I realize some people like the hobby aspect for it's own sake, but i sincerely believe that the majority of smokers don't and won't. There is a reason that out of nine million vapers in the U.S., six million are dual users. The cigalikes help these dual users to cut back, but not quit cigarettes altogether. If they were more satisfying, perhaps they could quit completely. Not to mention the over 40 million current smokers, most of whom have tried ecigs according to polls, but didn't stick with it. If they were interested in the stuff we use, they would've tried them already.
The more options we have in tobacco harm reduction, the better. I don't care if you use a cigalike, Pod mod, Ego setup, mech mod, DNA 200 or whatever, as long as you aren't smoking. Likewise, if the iQos, Ploom Tech, or a [removed] vaporizer helps some smokers transition, i support them. The same goes for Snus etc ... If you don't light it on fire, it's safer !
