Tom's Hardware has written a new Neuros II review. If you recall, the Neuros is an audio player with an unorthodox design. Instead of being an integrated unit, it's actually two devices in one. The first is a smaller flash-memory based unit that actually plays the tunes. This small bit docks into a larger shell that contains the harddrive storage area.
It's a novel concept, but it never really caught on. Furthermore, as time has worn on the chunky Neuros comes off as a brick compared to the leaner and meaner crop of current audio players.
Still, the Neuros is probably right for someone and the fact that it supports open source is also a plus.
If you are looking for a portable MP3 player that you can jog or exercise with, the Neuros is not for you. The player is much bigger and heavier than the small Ipod or iRiver MP3 players. Of course, if you do jog with the Neuros, at least you can use the Neuros player as a self defense bludgeoning weapon!
