Let's be real here:
Someone was going to make this software, whether it was Apple or not. A hack was made almost immediately, and better products were sure to be announced. So, Apple got to the plate first, so they can stake claim to the idea.
Since the success of the iPod, Apple is focused on making mainstream products. They are making a move to attract a greater mass audience. They've realized that people aren't going to switch to Mac hardware because of Mac OS X. Your average Joes don't understand what an OS is - they either know Windows or they know Mac and they don't want to have to re-learn anything.
So, how do you get them to switch to Apple hardware? You make the switch painless, in fact, you make it so they don't have to switch at all. The Mac becomes the next iPod - a must-have toy for yuppies and then maybe the mainstream. The OS doesn't matter. It's about the hardware now.
People interested in trying out all aspects of their new toy will give OS X a try. They might like it better, they might switch full time. They might not.
For regular Mac users...
We can now play PC games - the game developer community has proven over many years that they simply are NOT going to port to Mac. Too much hassle for too little return. So, if we can't bring the games to Mac, then bring the Mac to the games.
For Pro Mac users...
I can use Photoshop et al on my MacBook while I wait for Adobe to release the Universal binaries. Same goes for other Pro apps. Will I buy Windows versions of everything? Um, no, I will borrow.
For Pro PC users (creatives) ...
Windows users can do their day to day business as is - and now they can finally get a taste of Final Cut Studio, Aperture, Logic, Shake and anything else Apple has up it's sleeve.
Mac users aren't going to be lured into switching to Windows. Windows is awful, we know that, that's why we use Macs. Hence, Mac software companies will still have the same demand they have now -- from Mac users. We have always been a niche market and probably always will. But that market won't go away. As long as there are people to buy the products -- software companies will continue making them. They'd be idiotic not to.
You also have to remember that Apple is working directly with Intel -- so the machines we'll be seeing in the future are going to be insane compared to PC offerings. That means that even if people want to run Windows - they are going to want a Mac to do it.
My guess is that boot camp will wind up being a more sophisticated app that (hopefully) allows windows to run within OS X with no performance hit. That would give Apple a clearly superior OS.
If not, they should buy Parallels...

and make it happen.
