Joining the crowded field of low-cost digital audio players, the Evergreen DN-2000 is smaller than a keychain and able to play most standard non-protected file types (MP3, WMA, etc). It relies on SD cards for storage (not included) and has no screen, much like an iPod Shuffle. Where this dainty player distinguishes itself however is that at a cool $19, it´s virtually disposable.
