Working for O'Reilly and dealing with open source, Unix developers everyday, I can tell you ... these are people I want on my platform.
It's true, they're smart. But just as important, they have passion for their craft. Now I know I'm making general statements here, but that's because these statements are generally accurate IMHO.
If I could have any group of computer geeks on the planet come hang out on my laptop, I'd take these guys ... hands down.
They have so much to do with my positive outlook for Apple's future.
