I am not convinced by that. I think there is also a large difference in their MiniPCI cards compared = to their connectivity hub in their SoC. The Bluetooth side for example = is largely copying existing drivers, hacking their vendor specific = behavior in and then throwing it over the wall. Regards Marcel
