Moved from SE to 12 mini, now a 13 mini - just bought used last year. Will likely hold on for another year or two. Desperately want a small screen. There just seem to be no options.

Re: thumb - I have found some gesture to pull the screen down halfway so you can reach the 'top' part without moving your hand. It's close to OK, and it's almost second nature now, but still annoying.
