The first bottleneck is the keyboard. Until we have AI to understand high level mathematical intends expressed in spoken natural language and translate that correctly to code, it will be easier and more efficient to use a keyboard and formalize your programs yourself. There’s a youtube video showing how a guy programmed emacs macros, to be able to write code by speech... Then of course, the small screen size. But here, the resolution is good, we’d only need a way to, project it on your retinal. You can do without the phone screen, with somthing like the googleglasses... So, what is usable today, is the tablet with a bluetooth physical keyboard. Well, if you find a place to put them down, like a desktop. On laps, laptops are much more practical, since the keyboard is attached to the screen, which allows you to retain it with your hands! Otherwise, there are full IDEs on Android allowing you to code and generate applications directly on the phone or tablet, if you can solve the ergonomy problems.
