Hello all, first post here. I'm a PC user and not very experienced with macs I'm afraid. My old-man has 3 macs, a G3 - OS 9, G4 - 10.4 and G5 - 10.3. He works across 3 macs as he's a graphic designer and has a few things like scanners and printers which he assures me only work on the G3. I am trying to persuade him to get an iMac, i5, 27", (something like this). I know very little about macs but obviously I can Google and find answers, however as this is a slightly more complicated situation, I wanted to ask here for advice. How easy will it be to transfer all the data over to a new iMac, what is the best way to do this? Is it possible to install OS9 as well as the latest OS onto an iMac so he can switch back to applications he uses on the G3? Are there any obvious problems when moving from a very old set of macs onto a more recent model and OS? Thanks for your time.
