Can someone who positive to this story explain why?
I didn't vote positive (I have a MacBook mini of my own that I enjoy), but if I were to guess, one reason might be the reassuring news in all this: Apple doesn't plan on using the Atom in any of their computers. Remember when people thought they'd stick it in the Mac mini? That was scary.
Now if they'd just drop support for Intel video we could all rest easy.
Anyway, I'm pretty sure this isn't going to stop anyone from continuing to run OS X on their netbooks. People run 10.6.1 on AMDs. The guy who "faked" 10.6.2 running on a netbook seemed to have it running somehow, even if it took swapping out the kernel. This is just a speedbump.
