It uses one standard AA battery. To answer your other question, the USB cable is proprietary (like 90% of all digital cameras and mp3 players), since the connector on the MD side needs to be flat and small (the B connector of a standard USB cable is WAY to squarish and big).
Once you get used to the various software, and get over the fact that you need to convert everything to ATRAC3 (takes about 10-15 seconds per song on a Pentium 4 system), you will realize that this MD player is in almost every way superior to the various portable MP3 players on the market. No, it is not the smallest player around (I also own the Toshiba MEA220, and I am pretty sure it's the smallest/lighest mp3 player in the market), but it is a good tradeof between hard drive based players, and flash memory based ones. Again, you will easily get between 35 and 40 hours of playback, even 50 hours on the 66kbps (LP4) mode!!!

Minidiscs cost about $2.00 for each disc (which can store approximately the equivalent of 128MB flash card), so there is no need to keep on erasing your discs if you buy a few more

On my Sony CLIE, I spent $40 per 128MB memory sticks last year, and I find myself constantly deleting songs to put new ones in since there is so little room (and I can't keep on buying $35-$40 flash memory).
