Phil Gyford has produced a fantastic blog post, in which he's experimented with data input times on a range of devices, from an iPhone, to a Mac laptop keyboard, vintage Apple Newton message pad, and two flavours of Palm - a phone and a PDA.

His results are intriguing and not at all what one would expect.
