I know this day will come. Now you get two animals in one. Dual boot is now possible in Mac from this news here and I'm sure Apple will officially include this ex-factory pretty soon.
Mac has been something that I want to try as Apple II was my first computer. Since Microsoft has conquered the world it is a bit of a steep learning curve to climb for the Mac OS. After all once in a while at home I have real work to do.
With dual boot on a Intel inside Mac I would play with the Tiger and still deliver work on a single machine. Now bet how much sales boost Apple will get.
