At those prices I'd go for a beagleboard instead. It's got the sound and video output capability and the USB. Add WiFi if needed, and use VNC or a modified NX for display. For video it's probably better to stream the file to the beagleboard and let it do the decode locally. _______________________________________________ Openmoko community mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/community
