Well, you can replace the phone with a USB dongle, but there's no suggestion by Nokia of anything other than WiMAX for WWAN. USB dongle plans are generally data-only, of course, with no tethering issues. Cradlepoint is also an option, so you don't have another device hanging out the end of your tablet, but either way you have two devices.

Yeah, 3G in-device is technically feasible, but Nokia's not doing it.

If you want a raw network comparison, without regard to device availability, of mobile WiMAX vs. 3G, it boils down to: WiMAX is faster.
But I'm not sure the extra speed is of any practical use in an N810; CPU usage may limit throughput anyhow...

Tso, I realize those aren't tech dependent, but we know what 3G costs and what its coverage is like, because it's already deployed. I was just pointing out that some excitement may be on account of optimistic assumptions that optimists make when they don't have facts.

I guess I interpreted this thread as being more N810W aligned, while some of you are speaking more of WiMAX in general. My remarks should be understood in that context.
