Pros: small, lightweight, doesn't need a power outlet

Cons: not entirely plug-&-play, an optional case would be nice

Overall Review: At first I couldn't get my Tablet PC to recognize the device when it was plugged in and I was afraid I'd have to send it back. I did a little digging around online and ran across the suggestion to plug it in while the PC was off and then turn the PC on. Presto! It works!
