In the past few months, I've worked on Mac Laptops that feature both OS X and Windows.

The first project was connecting the Windows side of a Mac to a Server for access to corporate software. This Mac, using Parallels Desktop, was pretty easy to work with. Once toggled to the Windows personality, the networking and ports all worked just like they do on native Windows PC. Switching back and forth between OS's is just a keystroke away.

My second project was a Mac with Boot Camp. This one required some extra work to get the proper Windows drivers for the network adapters, sound and graphics, however once installed correctly it worked just fine.

One big advantage of Parallels versus Boot Camp is switching between OS's; Boot Camp - complete reboot - 3 to 4 minutes, Parallels - keystroke - 3 to4 seconds. Another big advantage of Parallels is the ability to share files between OS's. I strongly recommend Parallels versus Boot Camp (or other dual boot systems). In fact, the advantages are so many that I signed up to be an affiliate for Parallels (so if you buy using my links, I'll get a small commission).
