A few points to the adolescents who posted here
On the legality of Open Tech's actions
As long as OpenTech have some sort of disclaimer on the information they distribute which warns customers that Apple's EULA explicitly rules out the use of OSX on any non-Apple hardware and that consequently OSX is not supported on their gear, then they might legally be in the clear and Apple is unlikely to care. After all, the inconvenience of having to go through some hoops to install the operating system, the uncertainty whether and how well it will work in the end, that all makes the offer rather uninteresting for most people.
On Apple's purported reconsidering their move to Intel
It is unlikely Apple are questioning their move to Intel (as has been suggested by one of our adolescent friends who posted here) because Apple's market share, revenue, profits and share price all have gone up spectacularly as a result. Apple is a for-profit-business, as long as their business is good and their future prospects also look good, neither the company nor the shareholders will have any regrets.
On the significance of people who use hackintoshes
People who are using hacked install DVDs to install OSX on non-Apple hardware are a negligible minority. Adolescent posters on this board give them far too much weight. Most people who are seriously interested in a Mac will just go and buy a Mac. If they are on a tight budget, they might buy a second hand Mac or a Mac Mini, but they won't use a hackintosh. In this respect it is important to remember that most people don't build their own PCs from components either, most people buy DELL, HP, Acer, Lenovo etc etc. The price differences between those vendors' PCs and comparable hardware from Apple are mostly negligible. Most people don't even install their operating system. They use their computers the way they were delivered, with the OS preinstalled. Consequently, most people cannot be bothered to hack a non-Apple machine to run MacOSX, if they want to have a Mac because of MacOSX, they buy a Mac. Of course, there is also a group of people who try out those hacked OSX DVDs simply for curiousity. Either way, those hackintosh installations done by individuals are not anywhere near as significant as all the geeks who get excited about this stuff would like us to believe.
On profit margins of companies and Apple in particular
BTW, Apple's margins are known, even if only roughly, but unlike some adolescent poster claimed here, their markup is not 200%. On lower end products such as the Mac Mini, their margins are somewhere below or near 20% and for high end product such as the MacBook Pro, their margins are just below or equal about 30%. That's a good margin in this industry, yes. But outrageous it is not. It has made Apple the only vendor which has been consistently profitable during the last five years. During that time, while Apple was profitable, other vendors lost money, for example HP lost money on their PC business with a margin of 1% per unit just as often as they just about broke even. Such cut throat margins are not good for HP nor for HP customers because it puts the business at risk and customers may eventually end up without a supplier. Recently, HP have improved their margins and thereby improved the chances for their PC business to survive. Unlike most of the adolescent posters here who are still cared for by their parents paying for food and shelter, companies have to make profits in order to survive. Companies which make profits survive, companies which don't will die, no exceptions.
On the possibility Apple will ever license their OS
As for licensing MacOSX, it is quite likely that Jobs does have a plan somewhere in a drawer that he can pull out in case market conditions become right for Apple to offer OSX to other PC vendors as an OEM operating system. However, if this happens, it will happen on Apple's terms and they will be very careful not to repeat the disaster they experienced with licensing their OS in the mid 1990s. Whatever they do, they would want to preserve some kind of differentiation between their own computers and those of potential OEM partners. Most likely they would want that differentiation to continue to be both on the hardware and the software side, like it or not.
Note that it was made known that Apple had offered to license MacOSX for 1 USD per unit to the OLPC (One Laptop Per Child) project. OLPC declined Apple's offer but this shows that Apple are open to consider the possibility of OEM licensing if they think that the circumstances are favourable to them.
For example, Apple could build a separate OEM operating system based like OSX on the XNU Kernel, the Darwin base and the Cocoa API. In other words they could make a derivative that is OSX API compatible but that wouldn't have the exact same look and feel. The OEM operating system might even be customised in look and feel specifically for the OEM partner. Apple might only sign up the big fish, for example HP and/or DELL, and leave all other vendors to Microsoft. Apple might restrict support to a limited number of system boards and components or charge the OEM partners for developing and maintaining any drivers that might be required to support their hardware and components they would like to use. The resulting OS might not even be called MacOSX then, it might be called HP-DesktopOS and DELL-DesktopOS or whatever the OEM partners choose to call it. Like Intel's sticker "Intel Inside", Apple might then grant those OEM partners the use of a logo "MacOSX API compatible" or something like that.
Of course this is mere speculation, but if the opportunity arises for Apple to take advantage in some way, and if they feel they can manage this in a way that will not kill their hardware business, then it cannot be ruled out that they would do some form of tightly controlled OEM licensing. In no event do I foresee any situation where they would just sell their OS to everybody for every piece of hardware, in other words for them to adopt Microsoft's business model, that is simply not going to happen.
On the possibility that another company clones MacOSX
There is also another scenario that cannot be ruled out, that some other company will put some effort into assembling a MacOSX clone OS. This is not as difficult as it might sound. Apple's kernel, many of the drivers and the base OS (Darwin) is already open sourced. That leaves the Core Foundation and Cocoa APIs for which the specification is open and independent open source implementations exist. Some company which wanted to sell their own MacOSX clone OS could fund those projects and integrate all the parts into their own version, add some nice logos and graphics of their own and sell it. The logos and graphical elements would probably remain proprietary in order to make it a little more difficult for any competitors to fork without any further effort. They would also need to license some fonts. Yet, overall, the effort and cost to create a legal clone of MacOSX is not that immense.
Consider how much money a vendor like HP or DELL might be able to save in royalty payments to Microsoft if they could simply sell their own OS. The fact that MacOSX is becoming ever more popular is continuously reducing the risk for those vendors to create their own legal clone OS, because if they can market it as API compatible with MacOSX, and if they hire some decent graphic designers who make it look nice enough, they will likely find many interested customers.
On the possibility that open source projects such as GNUstep will deliver a decent looking Aqua substitute
It is also possible that the projects which work on the open source implementations of Apple's APIs (ie GNUstep) will eventually gain enough support that an entirely open source based MacOSX clone OS will emerge. They'd need some decent graphic designers though to make it look more appealing than what they have now. Yes, strictly rationally speaking, looks should not be considered as important as reliability and functionality, but in the real world, looks do matter a lot, even if only on a subconscious level. Any project that neglects look and feel is not going to be a winner in the realm of GUI systems.
