To the earlier poster concerned about the macbook wireless card -- it runs 802.11a, in addition to b and g, so I would not be surprised if it is indeed the Centrino-compliant chip.
As far as hacking is concerned, I think basically it is a good thing if it gets more developers, or potential future developers, or simply potential future consumers with a love of computing, familiar with the Mac platform and supportive of it. The switch to a UNIX-based operating system that has come with jettisoning Classic and moving to OS X has brought a lot of new people in, and this is how platforms get reinvigorated. I certainly don't think it is a threat to Apple's hardware sales given the complexities involved and the fact that the hacking required is enough to deter ordinary consumers like me . . . I think it ultimately drives software sales and software development, using as an engine people who otherwise wouldn't be doing much for the Mac at all. And for those who regard it as piracy, remember that OSX86 isn't about illegally copying software, it is about getting legally purchased software to run on something that was, until now, shutting it out.
