So the touchscreen and gps wake up the mini even after the car is off? Thats crazy. I plan to have the mini in my car in a dock like bugbyte made since I also want to use it in the house. I will have usb gps, usb touchscreen but thats about it for usb devices. I plan to use the dualboot to switch to windows if I ever want to use the gps, else ill use the mac side for the music and such. Did you get the special thing carnetix makes to add a 3rd output? I amthinking of getting that since I want to power my gps/ts, monitor and mac mini but I dont want the mini to keep waking up.
