Don't worry, bootcamp will work fine. There is no difference running W7 using bootcamp or on a Windows pc. I don't like to dual boot, so I'm using VirtualBox to run Windows 7. I only use a few applications that are Windows only and VirtualBox suits my needs perfectly.
I'm sure you'll love your new Mac. I made the jump from Windows about 18 months ago and have only one regret: I should have switched earlier. ;-)
