N800 or 770 instead?
It's no competition for an N800 Bluetoothed into a 3G handset then. Even a 770 will give it a run for it's money by the sound of it, especially when Expansys are selling the 770 for £65.
It's cheaper, but you get much, much less. You can't do voice or voice over IP, no local applications, out of Orange coverage it's a doorstop.
