Well with a transflective display you could do some data display even without powering the backlight. Many phones do this to display time etc, that would be very useful to have in my view. signature.asc Description: This is a digitally signed message part. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Future hardware options
I believe that a low-power-use auxiliary processor would be EXTREMELY valuable. There are LOTS of things that could run on a slower lower-powered processor, greatly extending battery life. At any time the high-speed high-power-use main processor can be fired up to handle the real heavy lifting. Moving the monitoring functions off the main CPU would be a GREAT improvement. - Add a small lowpower MPU like TI MPS430 to manage everything seamlessly when main CPU is down. Stuff like motion sensors, wake sources, battery management, maybe touchscreen, leds so there is an always-on guiding hand in the phone that is consistent and reliable ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
