I got given by an old couple an iMac G4 that they didn't need or want anymore (they were upgrading). I thought it was going to be a bit of a dog, but I was completely wrong! It runs great, and it now replaces the old dell family computer! It runs OSX 10.3.9 has a 1Ghz PowerPC G4 Processor with 768mb of RAM. Personally I think the iMac G4 is a better looking machine than the new iMacs! Apple really build their computers to last!
