Following the announcement last month that SanDisk will attempt to revitalize physical music media by introducing their slotMusic MicroSD cards, the company has unveiled a sub-$20 Sansa MP3 player made specifically for the new album format.
As you can probably imagine, there are virtually no features to be found on the new player - no screen, no internal memory - so you just need to pop a slotMusic card into the microSD slot, plug the included headphones into the standard jack on the right edge, and hit play. Although it isn't stated explicitly, you can also use regular microSD cards to play your own DRM-free tunes.
The SanDisk Sansa slotMusic player will also be available in a variety of branded "bundles," offering an album's worth of songs plus extras on a 1GB SlotMusic card, for about $35. Personally, I'm a little curious to see how the cheap slotMusic player and cards do in the market, though I doubt they'll make much of a dent on the music scene.
