They should just throw these cases out the window and work with companies like Psystar to compete with Windows based systems. I guess they make too much money from the blatantly overpriced hardware they're pairing with their OS.
Don't get me wrong I'm not a fan boy. I'll never own a mac but I'd love to see apple work on making their OS work on all PC hardware and go completely software based. They'd probably gain a lot of sales and market if they would do that. I could see dell and other manufacturers picking it up and offer that or windows on their PC's.
The more hardware drivers you introduce, the more likely you are to see conflicts, which means the more testing you must do, which means the more production costs, which means the end product goes up in price. You would end up seeing OSX being comparative in cost to Vista, there would be people complaining about the lack of support for certain pieces of hardware, there would be MORE blue screens and everyone would just keep complaining.
I don't care to use Mac's at all but really, it is Apples software, they can do with it what they want.
