Look at your mouse, the one you use on a daily basis - unless you use a trackpad of course, which isn't the same, so imagine it's a mouse for a minute.

And a variant has been pictured this week with North Korea leader Kim Jong Un in a photo published by The Wall Street Journal. It even seems to have been placed on top of a computer console taken from the set of Dr No, if you need more convincing that it is up to no good.The latest Logitech Trackman Marble promises "all-day comfort" - perfect for those War Games-style manoeuvres - and forward and backward buttons - although it's unlikely you can reverse a full nuclear strike.But most scary of all, Pocket-lint founder and CEO Stuart Miles has admitted that he used to own one of the trackball devices a few years back. Hmmmm.... We can see it now. And he's recently bought a white cat.Does Amazon sell giant lasers?
