Well, it can't run OS X and Windoze at the same time, which an Intel Mac,with Parallels or VM Fusion can do quite nicely.

As for real world applications, I wonder if Mike is using Logic Studio, quite the fine Mac based recording software, which does not run on Windows. Likewise, users of Final Cut Pro or Aperture need their OS X foundation.

PCs are great for the "mass market" and yes, there are many advantages to them, but viva la difference . . .
