Don't know why it's called OtterBox, really. Maybe because it has a hard outer skin? Like an... Otter? Erm. It allows you to shell mollusks on your stomach? Eh, whatever they were thinking, the OtterBox 1910 is a protective PDA case specifically made for the HP 6500. The water-tight seal should help if you're heading in for a swim and it does look fairly tough in case you've got big otter plans. Comes in yellow and black. Retails for $129.95.
