Since OS X versions are named after big cats, I can't think of a more marvelous cat than a Lion. Maybe the next one will be 10.8 Sabertooth? But I personally think 10.7 will end the OS X series. With that being said, I'm left in even more confusion. What will the new Mac OS be called after OS X? will it be called OS XI or OS 11? Neither of those sound or look very elegant at a glance. What do you think?
