This is **HOT**.
I have a lower-end unit like this (mine only has 256M). These thing are VERY GOOD voice recorders that also function as MP3 players. I cannot recommend these thing enough (if you need a voice recorder). The battery compartment pulls away to reveal a USB plug. But, here is the great thing--- NO DRIVERS NEEDED. This thing shows up as a mass storage device, and the recorded files are just .WMA files. This thing works great under Windows, Linux, and Mac.
AFAIK, this is the ONLY line of voice recorders from a major name brand that works nicely with Linux.
**EDIT**
Note that the package does not even include a driver disk. You don't need one. This thing will also work as a simple flash drive too. I love mine, and if I had the money, I would updrade to this model with 4x the memory.
