Samsung’s latest addition to the U-series mp3 players doesn’t do a whole lot for me, but it sure beats the heck out of an iPod Shuffle. The U3 will be available in 1, 2 and 4GB models with a 1-inch OLED display and 15 hours of hip hoppin’ fun. It also features an RDS tuner and supports MP3, WMA, ASF and Ogg files. The blue-lit rim on top conceals the USB connector and doesn’t do much else. The U3 hasn’t been ‘officially’ announced so there launch date and price are unavailable.
