So I picked up a Gateway M275 tablet on ebay for $150, figured I would give it a shot. It had damaged hinges and a broken lid latch and was generally scuffed up but working. A few repairs and some paint worked wonders. It is currently running Leopard 10.5.6 with the tablet working flawlessly thanks to Tabletmagic. Some stuff still does not work like sleep (bummer) and the various buttons along the screen but overall it is a smashing success!
