Flash drives have to have extras these days to get noticed. This one has a popular hook: Sudoku.
From Imation comes the Clip Flash Drive that rests on a carabiner clip for easy attachment to a backpack, purse, or laptop bag. The real bonus comes when you plug the drive into a PC. Suddenly, already stored on the drive is computer Sudoku, in four levels of difficulty. (That would be easy, medium, hard, and devilish.)
You get just one capacity with this special version of the already-best-selling Clip Flash Drive: that would be 512MB. You can pick up this fun device at Target stores throughout the U.S. for just US$34.99.
