More on Apple’s X11 implementation:
I worry that Apple’s X11 server will encourage more ports of this type, and that regular Mac users will be forced to use them.
You see, if Apple is to succeed in the Enterprise — and it must, especially with its shrinking educational market-share — then it must offer easy inroads for UNIX software companies to bring their applications to the Mac without significant code changes, a Very Big Deal in the cross-platform UNIX software development world.
Good points, one and all. I’ll only add this: There is a reason why Jobs made no mention whatsoever of X11 during the keynote. Those who need to know, now know.
