You should never feel the need or feel pushed to "upgrade" when you are happy with your current setup!
Can you find a better one? Maybe, and maybe not. There's the danger of chasing your own tail, if you know what I mean.
Everyone who manages to stop smoking or even reduces the number of smokes is a pro vaper in my book.
Edit to add for Least: you can make it as simple or as complicated as you want. I know an 85 year old lady, not very technically inclined, who managed to switch to vaping after smoking for 60+ years. It's possible, give it a whirl.
