Doxie – This scanner is a little annoying and slow — you can only scan one page at a time, one-sided — but on the plus side it is small, portable, and wireless.
Fujitsu ScanSnap ix500 – I love this scanner so much. It does 25 pages per minute duplex, all in color. If you’re on the go, you can also use the mobile app for wireless scanning from mobile devices. Very easy to use for the less technologically gifted, and very fast.
