I picked up two of these last night. It has two rebates - one for $30 from DLink and one for a 5" BW TV from OfficeMax. Problem is, both rebates require the original UPC, so you can only get one or the other. I even called OfficeMax's 1-800 number for rebates and they won't budge on having the original. The TV sells for $25 at CircuitCity so I opted for the cash.
So, it's a $20 32 MB MP3 player. It DOES store ANY kind of file and can be used for file transfers (it hooks up to the parallel port). It has a SmartMedia socket but the 32MB it comes with is on-board (not SmartMedia). You can add up to 32MB more of SmartMedia (I wish I could pull the Sandisk out of my IO and use it :)
I'm not sure how useful it would be as a file transferring agent for the IO (my IO is networked already), but it's a damn nice MP3 player for $20. BTW, the transfer software works on 95/98/NT only.
