Looks like Cowon fixed the major issues I’ve had with the M3 design. The new X5 is supposed to have menu navigation also on the body which features a nice color display. You’re not left helpless like myself when you have the remote in repair.
The device should work as a usb host, so if you’re lucky you will be able to store photos on the device directly from your camera. Nice upgrade I’d say.
Update: After a closer look, it may well be, that the mini-stick on the body still only controls seeking and volume. ugh.
