I currently use a 2006 Imac running OS X v10.4.11 and would like to buy an Ipad 2. I see where I need v10.5.8 or later and itunes 10.5 (i have 9.01) as requirements for the Ipad. Does this mean a whole new operating system? Is my Imac compatible for that? It is an intel core. With IOS 5 on the Ipad do I even need the Imac? I'm not getting much clarity when I call Apple and the nearest store is 3 hours away. Thanks in advance for any help.
