Can you elaborate on the windowing issue? I don&#x27;t have a mac anymore, and always disliked the menu at the top of the screen UX (which is the same as my Ubuntu).  I&#x27;m not sure what the windowing issue you&#x27;re referring to is.<p>Also, how is OS X moving away from UNIX? Or is it that major companies are moving away from UNIX? I&#x27;m not sure I&#x27;ve seen evidence of either of these.
