I think Apple have gone too far with the "Doesn't it look nice, isn't it incredibly small and neat" philosophy.
Within reason, I couldn't give a toss about how incredibly small and neat it is. Just give me a decent quad core, decent graphics option(s) and USB3 and I will be over the moon. If that's in a box twice the size, does ANYONE really mind? I certainly do not.
I couldn't agree more! Who cares how tiny it is. It's sufficiently small for all applications, including sitting next to a dvd player as media hub. It could easily be twice as big and still be very nice and small. The pc competition doesn't seem to do anything similar at this size, it's usually many times bigger, almost as big as the usual CPUs.
But well, I don't think this is going to happen at all. I don't think there'll ever be a mac mid-tower again.
