I don't think they are only for enthusiasts. I know multiple non-enthusiasts who decided to get the first form factor you described (regular phone size that folds in half) and love it. This style is also not way more expensive than other phones. Personally I will likely get this tri-fold style for my next phone, being able to open up to a small tablet is very useful for me. Your future is here. These devices have now proven themselves reliable enough for daily use by the average person. As long as you are ok with Android they are out of the enthusiast space.
