yes, the bios means that windows will not run on the new macs. Nor will any other i386 OS, however Vista is speaking about having support for many different types of bios and efi so maybe that will run.

I have a PowerPC G4 IBook, I love the Mac OS its brilliantly stable, and I can run many programs, and I can also run basic windows programs through virtual pc which is top notch not that I have to run Win32 apps very often.

I also have a PC for all my windows gaming like counterstrike, but it also dual boots with linux. Which is cool, but OSX is my favourite
might get a minimac for my other workstation instead of my linux box I have there.
