while digital imagery work is capable of being done on both platforms, mac is still in the lead. A public style mac isn't much good to anyone, but privately bought, customized macs are the best computer you can ever purchase. Pixar uses g5's now and they have up to 12 gigs in ram. The standard customization for ram though is only up to 8 for the average person, but you have to be willing to dish out a lot of money. They come with the markets most powerful dual processor setups. The most resource useful interface in existance. And they have a very good warranty.
It's just ashame mac doesn't put that much effort into their other equipment, only the g series'.
I'd suggest the lot of you check out professional grade G5's. You'll be blown away by them.
