Sony's just quietly unleashed a new water resistant, wearable Walkman -- the NWZ-250. This tiny little guy comes in both 2GB and 4GB capacity models, and apparently boasts an up to 11 hour battery life. Weighing in at 43 grams, this one's probably perfect for even the most weight sensitive of ears, and it'll be available in black, silver, lime green, and magenta. You'll be able to pick up one (or more) of these later this month for $60. Full press release is after the break.
