After a week of CES buffet food, I could probably stand to lose a few pounds. Maybe I should strap on some Fitness Technologies gear and go for a swim. FT specializes in sports electronics, offering three small players, each with a different wrinkle, and each advertised as "the world's smallest." In addition, to being small, the players are also waterproof. And when FT says "waterproof," they mean it; these players can be submerged in up to 10 feet of water (IPX8 rating). Swim, sail, surf, kayak, snorkel, ski, jog, scuba - you get the picture.
