I'be been working with PCs (Unix/Linux/Windows) since the mid 80's and I'm looking to do some "playing" with a MAC. I'm thinking of going with a used modle of some type as opposed to buying new ($$$), but I would like to make sure I at least get hardware and OS that isn't too obsolete. Here are some questions. 1) If I were to purchase a used MAC, what should a consider bare minimum? G3, G4, PowerMac....? 2) What OS should I consider as a minimum? 3) Are typical Dell and NEC VGA monitors compatable with some/none/all MACs or do I need some type of conversion cable? I have quite a few used 15 and 17 monitors sitting around. 4) What sites are there that experienced MAC users cannot live without. As you can see, I'm looking to do this playing with as little $$$ outlay as possible but still keep somewhat current on hardware/software. Thanks for any help you can provide.
