well its no doubt that MAC OS are one of the finest and cool graphical operating system.And it was not a shocking news for us that Apple now switches to dual supporting OS..wat i mean is now MAC OS is now supported by WINDOWS as well as MAC...
LEOPARD..is the operating system which is recently launched..and its really ultimate...may be slightly overrulling VISTA.
Leopard is just not an OS but its a user supportive us which makes us to be very very flexible and friendly with the interfaces.
Parental control is also the feature of the Leopard including ichat,time spaces and many features.
Well...just do try it..its under beta verion though..
