In case you're interested in Bluetooth keyboards, I bought a palm 3245WW from ebay for around $50US, and it was worth every penny. I use it with my N810.

Here are some of its great features:
1) It's quite large, has a full 5-rows of keys (no hitting Fn for numbers), 2) is a pleasure to type on (bigger and better than my netbook keyboard),
3) takes two AAs that last a LONG time,
4) one less step than having to plug the device in, and feels more 'stable' in use. IMO fewer cords is always a good thing (especially around a cuppa in a cafe),
5) has a built in adjustable stand which keeps the device securly in place, and
6) is a standard Bluetooth keyboard that will work with any device that supports BT keyboards.
7) really handy to just whip out and quickly use. Great for taking notes/composing emails/etc.
8) does not drain device power in a significant way.

Here are some cons:
1) It's bluetooth and as such insecure (from what I've read) -- I use the my device keypad to enter any sensitive information (eg. passwords).
2) It's a bit bigger than pocketable (unless you have *big* pockets -- or are wearing a coat), but I just leave it in my bag and it's ready to go.
3) On the N810 there's a terrible lag with text entry, but this is certainly the N810 implementation. I hope the N900 has better support built in.
4) Instructions for first-time pairing are a bit cryptic, but just ask around the forum if you get stuck.

All in all, I give it a hearty recommend. If you have the opportunity, try one out, or read online reviews!
