I heard recently that Mac was going to start building with "PC" processors-can't remember which-like Pentium or whatever. I was surprised no one else posted about this for some reason. It seems like a brilliant business decision on the part of Apple/Mac. They can offer a 2-for-1 system that can run Windows etc. while still able to run whatever Apple runs. I've also heard there is substantial overlap between Microsoft's new deal, Longhorn (?), and Mac's new OS, and Apple anticipates a premature and messed up launch for Longhorn followed by a solid lauch of the new Mac OS, so you can have your MS-OS and the Mac OS in the same machine made by Mac. My Mac friends like to say that Microsoft figured out how to make the whole world its beta-testers. I'm not diehard on either-whatever works for me for the money really. Any thoughts? Also, what is it about this 4 MhZ processor speed "brick wal" that can't be broken, leading to diffused processing (like GPU's and overlapping processors for different functions to make up for more speed instead of just one faster CPU?)
