To add to the good advice that's already been given, here's a consideration. If you decide to use boot camp, it creates a separate partion on your hard drive which contains windows to its own area. Then if and when you decide you no longer want Windows on your Mac, its easier to remove. If you use a virtualization solution you must remove that software, as well as the files it leaves behind.
Depending on your computer skills that may or may not matter to you. But it's worth considering. Also like they said, to switch between windows and OS X you must reboot your Mac. Yet that's not a really big deal because Macs do that quickly. So it boils down to personal preference. Enjoy your Mac.
