All the current generation of Macs use Intel processors now; the result is that you can configure the computer to 'dual boot' to Windows. There's nothing at all to stop you installing a small partition with Windows on a Mac for specific applications you may need to support (i.e. Flight Simulator 2004 in your case!

)
The technology is called Boot Camp, and I believe it's still considerd "beta" quality; I've used it though, and it's really pretty simple.
