Actually, this one deserves a 'keen'.
Technically is is the Flash Voyager USB 2.0 and it comes in 512M and 1/2/4/8/16G models, all with encryption and a lanyard that puts the Wii one to shame. The best part? They have an MSRP of only $299 so you can probably get them much cheaper, and in a week, with the way flash drops, they will cost about half that.
In any event, this puts some serious hurt on the makers of smaller HDs and other magnetic memory, they may be larger for now, but the gap is narrowing fast. You can read all about the the 4GB variant here. ยต
