I was changing channels on tv last night and came across a programme in which a demonstrator was extolling the virtues of the "LG Scanner Mouse".

This is a computer mouse with a small scanner built in. The idea is that you drag the scanner over the area you want to scan, until you've built up a complete image on the computer screen. Then crop the bits you don't want to use and process it as normal.

It sounds extremely handy for a lot of the fiddly scanning which I have to. But has anyone any experience of using one?
