I have been looking to make the switch to a Mac for a while now, and I'm getting more serious about it now. I have a couple of questions that I'm sure you can help me answer. A small note: at the moment, I can't spend too much money on a new computer, so I'm looking for something fairly cheap. Looking at eBay and craigslist, many of the Macs on sale are old G4/G5 models. Considering the fact that I'm not planning to buy new computers for 2-3 years, how do these models compare with the newer ones and are they worth buying? Specifically, I'm looking right now at a 1.25 G4 eMac that I think is reasonably priced: it has a Superdrive, its RAM is upgraded to 1GB, and it has a wireless card and a 2nd monitor video adapter. Plus, the owner is throwing in speakers and an iSight camera. It's priced at $600. Should I go for it? Another question is this: I've seen the previews of OS X Leopard, and I really like it. I'm thinking of waiting the extra 6 months and then buying a computer already with 10.5. But I also seem to remember that right before the release of Tiger, the prices on Panther Macs fell. Did this (and will this) really happen? If so, should I wait a few months and then buy a new computer? Thanks!
