Just got my Zen and finished downloading from Empeg to Zen. Must say the device is very nice. A bit on the heavy side but still better than most large cap Mp3 players out there. Pro:
Firewire
size
Capacity
Expandability (Recording FM Remote control)
Almost Empeg interface

Con:
Hefty sucker
TINY display
Weak backlight

I got a copy of Notmad explorer (Redchair software) and it is far superior for music management.
This seems an ideal device for hacking as there is remote access directly for contolling the device (via the not yet available remote control input) and I would bet one of the clever people on this board could rig a resonable display that would be readble in the car...any Takers??
