Since it's being discussed, and I never get around to doing anything with them, I have two N900 I would happily sell for 40 GBP / 50Euro each plus postage.

Both are near mint - one has a very light scratch on the screen.
Both owned by me from new, good keyboard, modem, usb socket.
Neither has ever been opened or repaired.
One in original box with all cables that I can find, the other is in an Ax-Alex leather case.
Batteries are good enough to boot the phone, but I've not checked the life of either one yet.

PM if interested
