Probably the only reason I would want it is to be able to play games when they come out for the PC rather than wait months for them to be ported.
Often the games are ported well and sort issues left in the original, but even so, months in games terms, if a lifetime
There are also a few other small things like no Mac version of the Oxford English Dictionary available which is annoying. But otherwise you can do pretty much anything on a mac you can on a PC, and often better (especially in graphics).
So, would I wish to boot into XP every time rather than Mac OS 10.x? No way!!! Really it is such a great user interface and much safer (I have not had one virus in 8 years of using Macs ;-) and now, being based on an Intel chip, and using the UNIX kernel as it's core (under the bonnet, unless you like tweaking), really Macs offer so much (for a smallish premium,like all good things). And if you want to talk about well considered, and good looking product design...
But the opportunity to choose to boot into Windows if I wanted to play a game or run the odd app I can't get, then sure, that's cool.
The question will be, when they hack the Mac OSX to run on a plain vanilla PC box, I wonder how many PC users will be tempted to use that combo
