Hanbit's XD-501 packs it in

If you're looking for a flash-based player that goes in the completely opposite of the minimalist
iPod shuffle, Hanbit's been showing off the XD-501. It's apparently their attempt to see how much stuff they could pack into 75 x 31 x 16.2mm (the iPod shuffle by comparison is 84 x 25 x 8.4mm), and here's what it's got: An FM tuner, FM transmitter, support for playback of MP3, WMA, ASF, and OGG
audio files, a built-in mic for making voice recordings, a four-line OLED screen, integrated 700mW stereo speakers
(which probably will be unlistenable), up to 2GB of memory, a miniSD memory card expansion slot, and a 25 hour battery life.
