Hmm... interesting. At first I thought this was a terrible idea, but thinking about it you're quite right that many threads belong in both sections because of the N800 and N810 hardware being nearly identical.

By keeping separate sections, a lot of users may be missing out on useful information, and some discussions will be needlessly duplicated.

This merger might be worth considering?

I don't think the name should be "hardware" because there's also the 770 tablet whose hardware is very different, and presumably the N900 will also be very different. But the sections could still be merged as "N800 and N810" or something like that.
