I say, WHO CARES!? One of the biggest points made about Apple's current lineup is that there is no "headless iMac". Which, even to me, seems like an awesome idea. But I also realize, that of every single apple tower ive owned, I upgraded only 2 of them. And currently those kinds of upgrades are now found in external USB/FW boxes. I fail to see how the arguement, "iMacs suck, they arent upgradeable, and you need to spend $$$ on a Mac Pro just to get some PCI slots and an upgradeable graphix card". How many people actually upgrade their machines, internally, past the original custom configs? Id guess the number is extremely low. Forgiving RAM upgrades of course. Those who need upgrades need a Mac Pro, I really fail to see a middle of the road that is even needed. If you truly need a fancy PCI card, most likely you are in the business that makes alot of money, otherwise you wouldnt need such a card. I dont know, I just get tired of people asking for a mini tower so they can upgrade...upgrade what?!
