Chose this scanner because of resolution and USB powered. Apple shipped it in its original box - no shipping box. The box came badly damaged and ugly tape all over the box. The scanner was missing two of its rubber feet. Tried it for a few days and discovered that it might have a limit on the area it can scan based on resolution - the larger the resolution the smaller the selected scan area has to be otherwise "scanner reports an error" message will come up and cannot scan. Reduce the scan area or drop the resolution and you are good to go. No information on this on the Internet - just my haunch. I will give it two stars because I am a fan of Apple although I expected better shipping. Lion readily recognizes the scanner and uses it. Canon does not have its own drivers for Lion. The disk that came with it does not run with Lion - thank Goodness. Returning this one and continuing to shop around.
