I've been playing with my new Octo-Mac and I love everything about it. It's as fast/stable/enjoyable as everyone told me it would be. However, there's one thing that almost no one mentioned before I got it and it's that it runs silent. Like "can't tell if it's on" silent. It caught me by surprise when I left it ripping DVDs at night and when I woke up there was no fan going crazy like my old computer. I thought it might've crashed or something, but that's just how it runs. That alone is worth the "Mac price premium" everyone talks about.
