I'm currently visiting family (halfway across the world from home) and have finnally been able to play about with the iMac (600MHz G3 Graphite) that my sister-in-law was given some time ago. It seems a pretty stable and decent machine, with plenty of HD space (almost 40 GB free) but only 128MB RAM. It can be slow to boot up. It's running OS 9.1 and she uses it for internet and writing documents. I am thinking of helping her upgrade it, but I don't know anything about pre-OS X machines. I think an extra 512 MB ($74 from OWC) would be worthwhile, but how about: 1. upgrading to Mac OS X? How easy is that? Would the iMac be able to handle OS X? 2. adding iLife (needs 1. of course)? 3. external DVD burner? It seems to me that extra RAM, OS X, iLife and a DVD burner would add up almost to a new Mac Mini, but then she would need a new monitor ... any advice?
