If the upcoming smaller Espruino gets an "inline" USB connector like the Digispark USB Development Board (I've heard rumours), it would be perfect for these kinds of things.
In addition to registering as a keyboard, the Teensy can also register as a mouse, joystick, MIDI device or even flight simulator controls(!). Also normal USB serial data, and Raw HID to communicate with your own Mac or PC apps. Lots of interesting uses!

(Sorry for bumping this old thread..)
I ended up buying a Teensy only because it can register as a USB keyboard while the Espruino can't.

I just read your comment from this morning on the related issue, I actually hadn't seen it :) I'm cross-referencing this comment to the thread where the discussion is happening now..
