Here is a cool Video Review of the Cowon D2. As you can see from the video, the reviewer is pretty impressed by the fast interface of the D2 and the comprehensive feature set. Navigation looks like a breeze.

The Cowon D2 is a portable PMP with full DMB capabilities and is also equipped with a 2.5" TFT LCD screen. It has a memory capacity of 2GB and one can also store voice memos using the integrated voice recorder or songs from the FM stereo receiver. You can also expand the memory using an SD/MMC memory card.
