I don't think Office file incompatibility is a problem, but the Mac and Windows versions of Office are just different enough to be irritating, sometimes. I use Excel many hours a day in Windows, and am used to certain keystroke combos that are not the same in Excel/Mac. I have not checked if macros run the same, that might be something to check.

That said, you can always run Windows on your MacBook using Parallels or Boot Camp, and thus have the familiar Windows environment - I think you can even toggle back and forth if using Parallels.
