I have an older white MacBook (Core Duo, 60 GB HD, 1 GB memory) with a faulty battery. Gazelle and other places offer less than $30, so I thought about about upgrading its battery, HD, and memory and giving it to my wife who only has an iPad and needs somewhere to store her pictures (so she can decide which she wants to print out). So would it be a good idea to use this for pictures only? If so, should I bother upgrading its specs just to be safe?
