Maybe I should have posted in here a long time ago. My N900, received 15 December, week 47, stopped accepting a charge 22 December. Considerable wiggle room. Sent it to the Nokia repair facility. They sent me a brand new one, received a new one three days ago 3 Jan. If this happens again it better happen before 31 Jan so I can get a full refund back from Amazon. Grrr. No clue what the production week is on the new one since they used my old box to send it back to me.
