Genealogists use handheld scanners more often than almost any other group I can think of. We scan documents at the local courthouse, old newspaper articles at the library, and photos while visiting a cousin's house. One of the more popular handheld scanners for genealogists is the VuPoint "Magic Wand." I own one and use it frequently. You can see my earlier articles about the VuPoint Magic Wand if you start at http://goo.gl/A4cwM.
I noticed today that M. David Stone has written a review of the brand-new VuPoint Solutions Magic Wand with AutoFeed Dock PDS-ST450-VP. This unit consists of two pieces: the first looks almost identical to the older Magic Wand handheld scanner but the second box is a dock that turns the first device into a manual-feed scanner.
