Given the patent-trolling that NetApp was waging against Sun for ZFS, perhaps Apple was wise to stay away (let's leave aside how depressing that is).

I wanted ZFS as much as anybody, but NetApp did push the state of the art in some areas of filesystem design and the first thing everybody who used NetApp said when they heard about ZFS was "cool, it's like a NetApp". Sometimes it's not trolling; it's just enforcing your rightful patents.
