My friend got an iBook off craigslist for cheap, he is not much of a computer user, he just wants to browse the net. The problem is that it seems extremely slow. It is running 10.3 I believe and has 128MB built in along with a 256mb stick. Would an upgrade to a 512mb stick of ram help at all? Would an upgrade to tiger help? He is trying to be able to watch YouTube videos on it in sd quality. Does anyone have an old iBook g3 they use for browsing and have any tips?
