I went and had a look and a play for 5 minutes today, my findings were:

- functions as a regular mouse and then as a scanner if you select a special side button, and the mouse is a little more bulkier than regular
- it has a clear window on the underside which is spaced a few mm off the surface so shouldn't get scratched affecting image
- with a fairly up to date computer it is quite quick to scan, and works easily by waving the mouse around (not needing to do in a straight pattern etc) and you can easily see what you missed on the screen and just go to that point and scan.
- ideal for text as has text recognition built into the software.
- max size is A# scanning, and need other software to stitch together - so a negative for a full playfield.
- graphic recognition is decent, and with colour blending it is a bit average like with a photo, not quite right with the colour but that is possible the computer screen used for the demo.
- BIG negative is that the surface has to be smooth and if you lift the mouse ever so slightly off the surface the scanning from that point locates differently and you have to start again - so you need to concentrate and not lift the mouse at all.
- works on XP and higher, 1 gb ram and duo processor minimum.
- doesn't work on a mac - I'm out, bummer was tempted.

overall definitely a good idea, but you need to take care not to lift.
