While you can run Windows software on your Mac, by running Windows on your Mac, if you are planning to get a Mac, you really should go for "the full Monty" and try out the Mac equivalents. Almost every major piece of Windows software has a Mac equivalent. This doesn't mean that any given software vendor has both a Windows and a Mac version. It means that if you can do capability "x" in Windows, you can usually do the same capability in Mac, perhaps with a different program.
If you allow yourself the luxury of trying this out (I call it "full Mac immersion", and it is what I did when I got a Mac) you will be amazed. If you just buy a Mac and then cling stubbornly to your old Windows environment, all you have is a pretty looking PC. If you buy a Mac and then immerse yourself in the Mac way for a while, you won't just have a pretty looking computer, you will have a new way of computing!
That new way is easier, faster and much, much more fun. Give it a whirl. Buy a Mac, consciously decide to work only in the Mac paradigm for say, a month, and then, at the end of that month, when you now have familiarity with both environments, decide what you want to do. At a bare minimum, you have that pretty new computer you want. In the best case, you not only have a new computer, but a new way of computing!
