Really, though? I remember you saying the N800 and N810 were co-existing devices forming a family; but they weren't: the N810 has completely replaced the N800 in terms of Nokia's marketing and, in some instances, availability.

Given the next device is orders of magnitude more powerful (by having the OMAP3 and graphics acceleration) it'd be utter foolishness on Nokia's part to try to maintain the N810 and N9xx on the same platform (however, as GeneralAntilles' pointed out: there'd be riots if they don't).

Of course, you might be hinting that there'll be a family of N9xx devices to cater to different needs. That would be big news - I'm not sure I'm convinced it makes the best sense, but would be very interesting ;-)

My concern about the HSPA focuses around three points:

1. Increases development and regulatory costs. Therefore production costs are, all else being equal, higher. Now, different components can change the "all else being equal" bit.
2. May diminish the focus on Bluetooth connections and keeping that a first tier option.
3. SIM-only broadband plans aren't massively advertised in the UK (if they exist). The closest are £15 ($30) a month for a 3G USB dongle. Not sure the SIM card can be extracted, but that's nearly doubling my line rental.

The HSPA bit will cost me in the region of $350 a year. That's a lot of money. If the NxxxHSPA was subsidised to free by a carrier on a £15pm contract, that'd be fine (but that reduces many of the benefits of the original two-device proposition). But I'd be surprised if they did that, given the feature set makes it look like a high end phone.
