Hi A general question: I have an inclination to purchase a second hand MacBook. I fancy a black one (but white would be nice) but I can't quite pick my way through the mryiad of offers out there in the UK, mostly on ebay. They all come with various marks, scratches, broken hinges etc. Some list non functioning batteries, some state only 1Gbyte of Ram. Could someone suggest what I should be looking for when buying one of these second hand. I would like someones personal point of view as to what cosmetic marks can be lived with and ideally what I should worry about. Finally: Can these still be upgraded today, ie Ram, batteries hard drives etc? I only want it word word processing, web surfing and to play my music. Any thought would be appreciated.
