I run Windows and Linux on the same machine and have not owned a Mac for a long time. The new Apple System X will run in Pentiums, unoficially, but might be sanctioned later.

However, the Cubase software is in the Wersi, and very possibly the B4 from Native Instruments for the 'simulated organ'. These softwares run in the Mac too already.

Since the concern is with music playing, I would'n give up hope in any direction.
