The bluetooth HDD isn't coming cheap I guess and you only have a limited amount of battery in the HDD and the W1060. It would be better if you would use the remote desktop if it is present in WinCE. I know for a fact that the SmartQ V7 does have that (in Ubuntu ARM), but streaming video is not so good.And Wifi should be at higher speed than with Bluetooth so I don't think it would be better then remote desktop.
