M-Cody M-20 Y.A.i.N.W.
Y.A.i.N.W. means of course Yet Another iPod Nano Wannabe.
This DAP will have sizes from 512MB to 2GB and will play Mp3, WAV, OGG and ASF files (so it’s already losing for not having AAC support).
Another difference is that the screen appears to be a monochromatic OLED instead of the Nano’s full color screen.
There have been worse contenders against the Nano, but so far, I think the closest thing to an iPod is a Creative player.
