iPod nano -- less than a quarter-inch thin. Announced at the IFA show, the TM-M1 is now available in 1, 2, and 4GB capacities with built-in FM radio (and recording). The 10-hour battery with 2-hour charge is pretty lackluster however, and that 1.5-inch, 65k color OLED won't win any awards either. Still, it's fracking thin and that has to count for something, right? Priced at about $100 for 2GB if you can track these down outside of S.Korea.
