Although, neither Apple nor Steve Jobs have indicated that they have any interest in opening OS X up to non-Apple-branded hardware, this admission by Dell is a rather huge boon for Apple. Up until this point, no large player in the PC world has gone on record saying that they would run OS X on their boxes if Apple opened up the platform. Considering that Dell is such a large player in the personal computing arena, if Steve Jobs were to decide to allow for this, most likely other PC manufacturers would follow suit, and there *could* be a chance of Apple challenging the Microsoft-dominated world of personal PCs.
Then again, if Apple were to do this, it would be a rather huge gamble and running OS X on multiple slightly different pieces of hardware would entail a lot of driver compatibility, which in my opinion is one of the many difficulties and weak spots with Windows XP. OS X running on more varied systems means more software support for drivers for different PC devices and could quite quickly become a big point of instability in what until now has remained a rather tightly reigned and controlled operating system.
What do you think? Should Steve and Michael sit down and have a talk?
