Now that I agree with--I just don't necessarily consider it a drawback. No software, no computer interface, no degree in computer science required for operation.
Remember, guys, in the end, all we're trying to do is heat a little PG & flavoring. The gee whiz factor with a PV containing more computing power than used in Apollo 11 is impressive--a huge novelty--but becomes an absurdity at some point, and raises more uncertainties than whether a thumbwheel setting will stay put in your pocket or not.
People always fear what they don't understand- its the lack of understanding that raises uncertainties- about 100 years ago the same argument was used against AC current by the guys who had DC infrastructure....
These are not very complex circuits at all- they are the core components of any/every well designed power supply. Unless you're the Unibomber (in wich case you wouldn't be here) you have similar circuits all over your house- they are in your computer, kitchen electronics, in portable electronics, and in your car -they are used for the sole purpose of supplying a specific voltage. I gave you a very simple explaination of the differences between a linnear reglator and a switching reglator- no technical terms...it doesn't require an engineering degree. Switching regulators operate with 80-95%+ efficience- Linnear regulators operate closer to 60% and sometimes less. Switching regulators generate pulses where linear regulators deliver constant voltage....
Its not absurd to pursue better safety, more power efficient circuitry, a more consistant vaping experience or even a different paradigm (setting wattage instead of voltage). That's why we're all here... we're not talking about adding an mp3 player or opening the garage door with a PV...
Now I'm going to get techcnical on you- there's a term called FUD - it stands for "Fear Uncertainty and Doub"t- its a sales tactic used in the software and electronics industries to steer you away from a new product offering... They guy with the simple/basic solution says something nice about the competitor by suggesting that the newer/more advanced product is is complex, or has too many unknowns, or is too new thereby casting doubt on it. Your argument about simpler/less electronics is better is FUD.
You don't need a degree in computer engineering or electronics to adjust these devices either. For someone that doesn't have an 8th grade education, perhaps it will be a challenge-
If you love your buzz then this will probably be a nice upgrade to it- more portable and nicer on the eyes- but you'll have shorter battery life and the dial will move when you don't want it to.... But you can't compare it to the L2 because it doesn't come close electronically. You have a valid point that there is a limit or point of diminishing returns but I don't see it yet...
