Personally, I'd prefer the device DOESN'T have a wide area radio like WiMAX and I'd prefer to have that as a feature of my cell phone (so I can tether to it like a modem) or as a feature of a seperate device (the way GPS is for the N800). I only say this because if you made it part of the unit, then you pay for extra weight and technology that marries that unit to a particular kind of wide area network that your favorite carrier may not support and will eventually become obsoleted down the road as everything eventually does. I would prefer that Nokia and other phone makers concentrate next-gen data on phones and make it so that they can "modem" the data through that wireless phone device so that ANYTHING (770, N800, N810, N900, laptops, etc.) with Bluetooth can just hook up.. even old systems as long as they talk Bluetooth.
