Query: Not very compatible with Vista

Scanner functionality is great. Software included with the scanner does not work with Windows Vista. You can download a Vista version from HP and get the scanner to work, but no matter how many times you install, re-install, search for patches, etc., it is cumbersome and gives a lot of errors. From a quick google search it's apparent that HP scanner software and Windows Vista compatibility has been a problem for a lot of people for a long time, and you'll find a lot of work-arounds but no solutions. HP makes good scanners, but so do a lot of other manufacturers, and if you use Windows Vista, it's not worth wasting your time with HP.
