Hmm.... no replacement? There are so many on ebay right now. I could sell you my N900. US (002) QWERTY, always used with a screen protector. All accessories and the original box available. Keyboard & and slider without failures, both smoothly going.
Best thing: the USB never broke (i'm careful), it seems really sturdy.

Cosmetic flaw: small (5x5mm) area of scratches in the lower right corner. Hardly noticeable on the housing, but a bit more on the metal. Re(pair|paint)able. But i currently can't decide if i could get at least 100EUR. Even if i'm mad because basic things - calendar sync, stuffer-free video recoding (HD DSP was what i only got to run once, and then never again) - don't work. Last time in the bank i just wanted to open two screenshots (1920x1600) with transaction details with geeqie - it froze. The default media gallery even couldnt open them. And don't tell it's messed up. It's just that too often software is **** / a hack-job , but nobody seems to agree on that. **** compiling on the device - i want basic things to "just work", that you actually need / have to rely on in daily life.
