Why it won't (Score 1)

In all reality x86 processors have a rather dominant market share. Unless apple does something rather drastic, it's going to stay that way. I've personally always been fond of pc's and I definitely like the ability to replace parts whenever I want(though they're taking that out of a lot of the prebuilt machines these days). Whether Apple's new operating system turns out to be a good OS or not doesn't really matter if no one buys the hardware. That is the real edge for linux you can put it on the machine you already have. Well that and there's a much larger community at work making sure things work properly and adding support to it. In the end what will determine the success of this OS is the success of the computers it runs on, and that future doesn't look terribly promising.
