I contacted a guy on gumtree who is selling a used G4 mac mini (512Mb Ram, 80gig HD) in my town. The price is £200. I know it's an old machine, but I want it for my gf who needs a new machine for word/excel, internet, iTunes etc... I have a few questions for those of you who have one/know a bit more about this than I... i) is this a fair price for the machine? The guy said it's 1 1/2 years old. ii) I'm going to have a look at it (too many rip off merchants these days), what on site tests for it would be best? iii) was there anything inherently unstable about this machine (hardware problems I guess)? As there is no applecare. He says it's never been needed to be serviced. Thanks in advance.
