Totally noob question about Macs... Until about 30 seconds ago, I was focussed on the idea of getting an iMac - the only one I have seen in a shop. It's only 30 seconds ago that I stumbled on the mac pro on the Apple site. Looks pretty cool, spec etc. Anyway, the basic question to you experts is... iMac or Mac Pro? (Assume existing models/specs, discounting any idea about 'updates' to the iMac.) Thanks.
