Here’s a little demo of the SanDisk Sansa slotRadio player that we reported earlier. The basic gist is a $99 player loaded up with 1000 songs spanning various genres. You can also buy genre-specific microSD cards for $39.99 that come with 1000 songs too. Think of it as the lazy man’s MP3 player. You can load up your own microSD card if you’re feeling ambitious, but most would-be purchasers will likely stick to being spoon-fed the music. I can already see these things sitting in airport vending machines.
