No, this is a bad idea. I'm buying an iMac next month and if I see the new one becoming aluminum I will definitely buy their leftover ones from the old generation. The small Macbook is always plastic and white and cute while the Macbook pro is always brushed aluminum. That's the way it was meant to be. Now, if the iMac, which had been plastic and white and cute ever since ever, turns metallic, it's gonna go to the PRO side. No no, that's not where it should be, that's Mac Pro's place. Apple is going to make a mistake if they make iMac aluminum, cause that's gonna depress buyers who love the cute white thingy. Just look at how inconvincing the shuffle and the nano have become. Now I'm resorted to only buying the video. I hope this transformation stops right here.
