Agreed. Don't forget about tablets too; I'd happily pay for someone to make Emacs usable with touch gestures and optimized for touch use (e.g. with a clickable, context-aware button row).

I'm waiting for Emacs to run natively on ChromeOS (or Android) so I can get a Chromebook. (I'm not willing to install Cruton or any of the native Linux hacks on a chromebook).
