Maybe with a hypothetical N820, which would be complementary to the N810 the way the N810 is complementary to the N800. This hypothetical N820 would have the following features:

- Screen like described by phi above (edit: If it's actually stronger..)
- And transflective, so it can be used in sunlight
- If Nokia wants to throw in that ambient light sensor for minimal extra cost I'm fine with that.
- 256MB RAM (up from 128)
- 512MB internal flash, if feasible (up from 256)
(those two may depend on what's actually available as an integrated memory chip. Could be that there's no such chip at the moment.)
- The leather pouch should have a little flip to close it, to avoid that the NIT falls out of it (which happens way too easily with the N800)
- Video throughput bottleneck of the N800 removed
For the rest, very close to the current N800 (the N820 will be an improved N800 in this scenario):
- No slide-out keyboard
- 2 full-size SD/SDHC slots

In other words, a pure, true N800 upgrade for those of us not matching the N810 target audience. As far as I can imagine the above feature set shouldn't be more costly than the original N800.
