The Fujitsu ScanSnap S1500 Instant PDF Sheet-Fed Scanner for PC ($415.99 on Amazon with free shipping) can scan a 50-sheet stack of double-sided documents at a 600-by-600-dpi (dots per inch) resolution, in color, at 20 pages per minute. It can also turn those scans into PDFs with the included software (Adobe Acrobat 9, Rack2-Filer, and ABBYY FineReader). This is a very handy way to archive important documents and reduce paper clutter around your home or office. And it's much easier to find an electronic document than to search through stacks and boxes of papers!
