Edit: I've been a fan of the netbook concept since well before the term was coined, when the Toshiba Portegé first came out. But my experiences with them, like everyone else, were disappointing. I'd love it if these new units had good performance.
However, I will also say that a touch-type keyboard on a phone is still awesome, and I will certainly be buying a PinePhone+keyboard when it comes out. I live in forlorn hope for the day I can evict Android from my life entirely (the Micro PC does not, alas, make phone calls).
Yeah, the inherent fatness of fingers problem. And the lack of buttons on those fingers other-problem.
Looking at the resolutions, 1280x720 vs 1440x720, I would have just expected the phone experience not to feel terribly different. Of course it remains to be seen how much the PinePhone software adapts to landscape in wake of the keyboards coming.
The Micro PC proves that we were sold a myth; that dumbed-down UIs were a necessary evil to enjoy computers in our pockets. They aren't. Pocket sized laptops work amazingly.
