I just got back from picking up a couple of Newton batteries from a fellow on Craigslist. One is a OMP battery(?) AND wall charger (Apple branded, part number H0017 and H1200 respectively), and the other is a NEW IN BOX MP2000 battery with the tagger still on it (a la Nigel Tufnel)!!!

Sweeeeeet! I have been bummed that my MP2000's battery has had nil for life lately.
