Ok I've been a long time PC user. And I've been thinking of changing to a Mac for a while and I've been comparing prices on several models of Macs. These are: a standard Power Mac G4, iMac 17" w/combo, 15" Powerbook, and a 14" iBook. Everything is within the price range I have set. I'm not very familiar with Macs as you will see. So I'm turning to ya'll for a few answers. What's the difference between a PowerMac (G4) and an iMac (G4)? I can see that the Powermac is a tower with possibilities for expansion and so forth, and the iMac is more of a single base with monitor attached. But are there any other significant differences, such as in abilities and so forth? (I know, an odd/stupid question. But I've never played w/ Macs. A couple friends have them and I'm taking a look in a few days.) When it comes down to it, I will probably end up either with the Powerbook, or PowerMac. Any comments on what is better and for what? Some of my friends like to network their PCs and play games (Diablo, StarCraft, etc). Would there be any difficulty in networking with them? I'll probably have more questions but I'll post them as we go along if that's fine.
