In my opinion, the most convincing feature of this particular N900 is the qwerty keymat with four cursor keys, which also seems to be in pretty good condition.

Too bad, the photo isn't focussed correctly, so it's hard to judge the actual condition of the keymat. For example, is that blur on the shift key just some dirt on the camera lens or is it wear on the keymat?

It would also be helpful if the keymat photo could be made while the keymat LEDs are on, because afaik, there are some pretty original-looking aftermarket keymats but without transparent letters.

That being said, I'm tempted, but not actually interested in buying it, because I'd just be doing it for the keymat.
I just wanted to point out, that the low-quality photos are not doing a good job in presenting the potential of the device.
