This is one reason that using my Mac and Logic didn't work out well in my case. Because I do iOS development, I have to be on the bleeding edge with regard to Apple updates. It would completely fark my music environment to do that.

Microsoft isn't good at everything, but they are quite good at maintaining backward compatibility. It's amazing that most software written 35 yrs ago still runs on the latest and greatest version of Windows.
