Just thinking of the old Acorn RISCOS computers. The motherboard used to have a ARM based CPU as normal, however you used to be able to buy a x86 processor that used to slot into the motherboard. Meaning, you could use the ARM processor for RISCOS, and the x86 processor to Windows nativly within RISCOS. Wouldn't it be cool if Apple did the same thing with PPC and x86 on the PowerMacs. P.S. Any old RISCOS users here?
