My 2003 Powerbook G4 (1GHZ) has recently been labeled by Apple as "vintage". Vintage is the polite way of saying they will no longer carry parts for and will no longer repair my long time friend. Figures since the Ethernet port, and various other ailments have since arisen. OK, time to hand it down to my seven year old so daddy can get a new laptop. My concern is, if I layout over 4 grand for the new 17" Macbook Pro with the processor, RAM, and HD speed upgrades, what's going to happen in 5.5 years? Will Apple deem that unit as vintage too and not replace the battery? At that price I may want to get more than 5 years out of it regardless of what new technology is around at that time. Do you think Apple could actually stop installing the new batteries after 5 or 6 years?
