Re: ZFS
While I'm sure Oracle's purchase of Sun was part of Apple's decision to drop ZFS, they withdrew from the server market at the same time.
OS X 10.7 (Lion Server), the first one to be bundled as a (significantly cheaper) add-on to the base OS was released in February 2011 without ZFS).
Many are happily using ZFS now, but letting it loose on consumer kit 5 years ago was going to be one hell of a risk.
