Apparently Nokia has an ample supply on N900 devices for in-warranty replacement. I had 4 (that's right - Four) N900's since I bough my first one this April 2011. Just, FYI.

P.S. Nokia happily replaced my N900 when USB broke and even toyed with the idea of giving me a different phone since I have "so much trouble" with my N900. However I couldn't come up with any other Nokia that I would like in lieu of my love/hate N900 experience. (N9 in not an option since it is not offered by Nokia on the USA market.)
