Good news, bad news and mixed news...
Good news for...
Consumers, now you can natively run Windows on the best looking and best performing computers in the world.
Apple Hardware, now they will attract PC users to try out their nifty computers without worrying about software not running on them.
Bad news for...
Dell, IBM, Sony and every single PC manufacturer. Usually PC users would not consider Apple because, it can't run Windows, but now, every single Intel Mac will compete directly with PC manufacturers, and frankly, the Mac is superior in all aspects, plus you get OS X! Its like a whole new brand entered the PC market, and its an awesome brand!
Mixed news for...
Apple Software, think for a minute here, Mac OS X and Windows used to compete from different hardware, Apple for the Mac OS X or PCs for Windows. Now they will be able to compete on the same computer since speed is no longer an issue because Windows can run natively on the Mac. People will be able to administer their computer through one OS and use the other to run specific applications for that OS. Basically the battle will be for which OS ends up being the "main OS" in which people usually work, and which OS ends up being the "bitch OS" which people use to run specific applications. If people like OS X better, then they will do most of their stuff on OS X and boot Windows when they want to play a game or use some Windows only software. The opposite is true. In my opinion, OS X is superior to Windows in most aspects, the only draw back from OS X used to be software that would not run on it, that is no longer a problem, so this means...
Microsoft will have trouble, why? Well, most people pirate Windows and Mac OS X, the true sales for those OS come from those pre-installed in brand-name computers (you can count OS upgrades too, but then again, they are pirated). Apple will continue to sell OS through their computers, and since people are likely to start buying more Macs (since they can now run Windows, and Macs are cute

), for every Mac bought, there is an OS X sold, but not a Windows sold. People will likely pirate Windows to run it on a Mac, or use the Windows disc from a previous computer. Again, Windows and Mac OS X will compete to see who ends up as the "main OS" and the "bitch OS". I honestly think that Windows will be the "bitch OS".
It would be awesome if somebody developed a tool that ran Windows on the background so you don't have to see its ugly face, then when you run a Windows specific application, it just launches it in "window" but you never have to deal with the OS. Sort of like when you ran Mac OS 9 applications on the X, that is the best analogy I can think of. Microsoft could do the same thing, but then again, why would anyone prefer Windows over OS X?
My 2 cents.
