Actually I'm pretty sure Intel has looked at it's sales figures and confirmed the truth that in the vast majority of cases, even enthusiasts rarely change their CPU's without changing the motherboards. So it really does make sense to combine them rather than sell them separately.
The results could be quite interesting, and any change to the PC H/W arena is exciting over same old/same old. It's just process...
I've taken apart most of my Macs at one point or another. They're not that locked down, although it's a bit ludicrous to upgrade anything but the memory on an iMac.
if you owned a manufacturing company, you would prefer your stuff not to be opened up either. Notice I say "prefer". When people open it up, it compounds the mess-it-up likelihood..
I think you guys aren't getting the full meaning of what I am trying to say, Apple does not just not want you not to open up the hardware. They don't want you to do anything at all, the operating system is closed and unyeilding, their software and well just about everything they do is closed. Heck they don't even want you to think. Just return the product becuase your unable to do anything with it and they swindle you out of even more money.
