Ugh, straight-key input is so hard to get right, when keyboards have such awful springs. Offer an iambic option, especially one that uses mouse left and right buttons, and it's much easier to implement a "paddle".

I've been wondering if a cellphone's accelerometer would allow you to simply nudge the front and back of the phone itself, in the absence of any physical buttons at all, and have it run through an iambic keyer in software.
