I don't get this argument. So many people (ie. The Inquirer

) expect Apple to release OSX for running on generic Dell type PCs. The only thing I can think of is that they like the operating system, but want to custom build their own computers, and so claim that Apple would do well to open their OS to any computer, which is clearly equivalent to a large, dead bull.
Apple don't care how many computers run OSX. Apple really couldn't care if half the people who bought Macs installed boot camp and Windows on their computers, and ignored OSX. Apple is a hardware company. Microsoft is a Software company. This is clear when you look at the prices of the operating systems. I can get OSX for about AU$130 (or whatever it is Edu), while the upgrade from XP to Vista Ultimate, really the only way to get a system with most of the features of Tiger, costs like AU$500, or something absolutely rediculous. Similarly, we can see that Microsoft DO care about how many people use their operating system, with Vista's limits on use with Virtualisation, and the fact you can only buy an XP upgrade, or a pack of Vista licences, which effectively leaves Mac users in the cold, unless they buy XP first, or more realistically and more likely, get their hands on a pirated version of XP.
Apple WILL NOT open OSX to generic, non-Mac PCs. EVER.
