So never used iBooks before and was curious to try one out. When I go into iTunes to check out the book it specifies: iBooks 3 AND OSX 10.9 or later REQUIRED. WHAT? I am happily running Mountain Lion and have no need to update the OS. So people not running Mavericks are S.O.L. in the iBooks department? So Apple is not interested selling us books unless we follow the upgrade path like sheeps? Am I missing something?
