I can’t say enough good things about the Fujitsu ScanSnap S1100 mobile scanner. It’s really the only peripheral I use with my MacBook Pro on a regular basis—other than a French press.
The S1100 has been extremely reliable in the three months I’ve been using it. And I’ve been using it a lot as a new parent who’s entered a whole new universe of medical and financial record keeping.
The S1100 scans fast, works off USB power only, and is small enough to slip in almost any bag.
If you have an iMac, Mac Pro, or other more stationary setup, you might want to spring for one of Fujitsu’s larger multi-sheet desktop models, but if you use some flavor of MacBook and don’t like to sit in the same place (like me), the USB-powered S1100 is the only choice in my opinion.
By the way, if you’re scanning a lot of sensitive documents like I am, you’ll probably want to keep them in a secure disk image on your Mac. That’s what I do.
