Agreed. Except I think proper styluses/digitizers, like what I gather one gets with the Surface Pro, and I enjoy on my Samsung Note 3 hold much better potential than multi-touch (there's a reason why artists and designers have been using digitizers for a long time).

Keyboard for text entry coding, digitizers for design/art/photo-work and possibly (multi)touch for richer, Smalltalk-like UIs. I've always thought three-button mouse weren't such a great idea (ergonomically) -- but a lot of the same things that work well with them (Smalltalk, ACME), should work fine with multi-touch -- as long as we evolve the GUIs a bit to take proper advantage.
