I installed Parallels Desktop for Mac on my MacBook Pro. Parallels Desktop is a great virtualization tool for Mac, as it allows you to use other operating systems pretty much as if they were native operating systems.
Once you installed Parallels, Installing Microsoft Windows on Parallels is so simple, I don't even have to explain the process. Just insert the Windows Installation Disc, choose Microsoft Windows from the drop-down box of Operating Systems, insert the Windows Key and the installation will take place automatically. It's far more simple than the normal installation of Windows on a PC.
And then all you have to do is just use Windows in the same way as if it was running on a PC. Parallels even allows you to share some folders with Mac OS X, which makes transferring files between operating systems run seamlessly.
