MuVo's 4GB MicroDrive

Ok, here's the deal. Go and buy Creative Nomad MuVo2 MP3 Player with 4GB memory, then take out 4GB microdrive and replace it with other cheap CompactFlash card. The trick is that this 4GB microdrive has CompactFlash interface and costs much more when sold separately.

Here's the original link and comments. I didn't try this myself, but soon hopefully will.
