What Mac programs do you want to run? Actually there is no Mac only programs that I kknow of except those from Apple. Like Aperture, FCP and the standard iLife and iWorks programs. All other software usually has both Mac and Windows versions.
As to the "i" programs why would you want to run them. They all S.U.C.K and there are better windows programs then any of them that do a better job and are easier to use. This coming from someone that has a Mac computer and can't figure out why anyone would say Mac's are easier to use, they aren't.
