So a seller on eBay who seems reliable (good communication, lots of +feedback) is selling a 1Ghz 12" PowerBook with Superdrive and 80GB HD for about GBP400 (USD750) less than its equivalent from the Applestore. It's a refurbished unit and he has been upfront and said that it has two dead pixels on either side of the screen. My current iBook (G3 700Mhz) has no dead pixels, so my query is do other users think the deal is worth it?
