Uh... quite tough, isn't it? That would require a major hardware work (second charger logic for 5V charging, power switch, more pins in the battery pack, extra power regulator for 5V, etc.). That would mean roughly an addition of 20 to 40 extra parts on the PCB. Sure, could be done, but is a quite complex thing. IMHO too complex to achieve the goal. I am personall already quite happy with Bluetooth. Wifi requires to have a good power managed Wifi chipset like in the Nokia 770 or N800 - else Wifi is pretty usefless. I am willing to wait for FIC to dig out such chipset and integrate it directly into the hardware design. > Richard.
