Just when I thought I had cracked the keyboard thing by getting a keyboard with blank keys, along comes the Optimus keyboard, which has a changeable display on every key. Certainly a brilliant concept – the problem with programmable keyboards, of course, is always remembering which key you mapt that brilliant macro to.

This offers a genuine innovation. As far as I can see, this is a proof of concept. The challenge will be in the implementation – to what extent will grit and dirt and fiddly software decide whether this will turn out a workable solution or just a cool gadget for keyboard junkies?
