I was hoping devices like this (https://www.fxtec.com/smartphones/pro1x) would catch on, but I think people have given up physical keyboards.
(obviously flip out phones have a lot of moving parts to get damaged)

I think the ideal form factor for a proper development phone would be the Astro Slide (https://www.indiegogo.com/projects/astro-slide-5g-transforme...) – I haven't personally used it but I can imagine it's the smallest size possible for proper two-handed typing. The F(x)tec was a two-thumber instead.
I also had a Gemini PDA, which is basically the Psion 5mx keyboard glued to a shitty Android smartphone. Such a nice keyboard, but such mediocre and unsupported CPU...
