Those explanations are a big deal. Complicated, inconsistent systems will turn off many people. Just read about the difficulties here with equipment and juice and you realize there's a lot of room for improvement. And we're supposedly "advanced" users with lots of knowledge. It's tough to see that sold to a current smoker who's not super motivated.
As an ex-smoker and not someone who started just to blow clouds, I know if I had jumped straight into open systems I might not have stuck with it. That cigalike got me off cigarettes. What drove me to open systems was the quality of the experience, and the expense of all those cartridges.
Getting a smoker straight into an open system can be a struggle unless they're very motivated. The one bright spot I do see are the number of "new" closed systems coming out that will offer a user a much better experience than a gas station cigalike. From there, a user will either remain with it if satisfied, or perhaps move on to an open system if they want to possibly improve their e cig/vaping experience.
I was the opposite. I tried cigalikes, and didnt last 3 days. In the junk drawer they went. It wasnt until I tried a 2nd generation open system that I was able to give vaping a go. It worked, cigalikes didnt.
(For me anyway)
