FYI:
There's been a challenge (with prize) out for anyone who can post instructions on how to dual boot an Intel Mac into XP (and OS X). So far, no dice. Vista should install without problems, but that's a ways off.
OS X has been "cracked" to run on generic PC hardware, but tends not to get full benefit from the GPU unless it matches that found on Intel Macs (so Intel GMA950s, Radeon X1600s etc. work dandy; other GPUs not so much).
The Core Duo (Pentium T2x00) CPUs used in most of the new macs (the base Mini uses a Core Solo) have been benchmarked against AMD desktop CPUs and other Intel CPUs and hold their own very well. The 20" iMac is, running native software, probably the second fastest Mac available (after the Quad G5) when running native, optimized software -- and consumes no more than 120W (for the entire system, including monitor and 256MB x1600 video).
