Dell is offering unbelievably low prices on Lexar Media JumpDrive Secure USB keychains. These are the only ones on the market that support password protection on both Windows and Mac OS X, and they're pretty decent little devices. Nice shape and size, very sturdy, though the cap can come off a little too easily.

for more info. The best deal is the 512 MB model: free shipping, total cost is $79 after the $30 Lexar mail-in rebate. [Note: I had to use IE to order from Dell's site; Mozilla didn't work.
