What are the historic OS X versions' 'selling lines'? OS&nbsp;X 10.7 (Lion) is advertised on the Apple website as 


  The world's most advanced desktop operating system advances even
  further


The beta page for OS&nbsp;X 10.8 (Mountain Lion) goes:


  The world's most advanced desktop operating system moves even further
  ahead
