Regarding typing, I think a lot depends on the keyboard you are using. With default keyboard, yeah there's no way I'm typing more than a couple of sentences, as you said. But with a better keyboard (e.g. Swift on Android), I can easily type a few paragraphs. Because text prediction and spelling correction is so damn good, I just need to press the keys roughly near the one I intended (e.g. jekko -> hello).

Although, I could type natural languages, there's no way I'd be typing code. Simply the number of special characters required makes it very slow and frustrating. And if you need to be mobile, you can just buy Chromebook (or similar device), install Ubuntu/Arch/whatever and happy coding.
