Linux on a Mac now is about as silly as running Linux on a Sparc machine. It can be done, but there is a better Unix built for the CPU sitting in the box.

Is Solaris really that good? I've heard it scales better than Linux on really big iron (say 8-way) but that Linux is overwhelmingly faster on 1- or 2-cpu kit. This was a while ago now, but I heard of a theoretical astrophysics outfit where they had one Solaris machine that ran the (actually quite good) Sun optimising compiler, and everyone else had Sparc Linux machines to actually run the programs on.
