Summary: I use this in a law office/buiness setting with an IBM laptop running Windows 2000. The problem is if I do not scan something for about an hour, the scanner loses its connection and you have to turn it off and back on to get it to scan. A royal pain in the you now what since the power button is on the back. I called Visioneer support and they said "That is the way it works - if you do not use it it loses connection." I think that is BS. My HP did not.
