This sounds interesting: A
new MP3 player from Archos, the Gmini, which is claimed to be the smallest 20Gb MP3 player in existence (which means it's probably based on one of those
1.8" sub-notebook hard disks). The interesting part is that it will work with plug-in accessory modules, including a voice recorder, a photo viewer and music composition software (which could be anything from a glorified ringtone composer to a Cubase-like studio package to a loop-based dance-music production toy).
I recently purchased a PhatBox. It's the greatest thing ever. It's like having a 1000 CD changer in the trunk. I highly recommend it.
