I'll take three (or maybe more) of the hinged, though I would like a 360 version for my n800 as well.

One other thing that would be useful would be a short (maybe retractable) cable with micro-A on one end and a mini-B on the other. The camera, GPS, powered hub, and most other things I plug into the n810 use this connector.

On the powered hub matter, injecting 5v might make something work, but then the device is lying if it says it only needs 100mA. The N8x0 will reject anything that tells it that it requires more than 100mA over USB (hence the 2G iPod works because it recharges/powers over the Firewire slot, but later ones won't work because they want to be recharged via USB even though all have batteries). I just got a few small portable hubs with external power connectors and they solve the problem.
