Running Mac + Windows in Parallel?

Every time I ask a PC audio or video question, there seems to be a chorus of fans suggesting I switch to Mac.

I would potentially be interested in doing this for my personal stuff, but its seems a bit of a pain given that all of my work lives in a windows envronment.

I heard recently, however, that Apple may be responding to users like me in that the new machines will run both windows and Mac? Simultaneously?

Does anyone have any experience with this? That might be the ideal solution for me, as even if Mac does run Office etc, I dont really feel like spending money for the Mac compatible software that I already have.

Any suggestions greatly appreciated.
