Thanks for your comment. The Mavericks OS news is separate from the iPad and computer news.What Apple announced today was: (1) its new Mavericks OS for its computers/laptops, and that (2) Apple would no longer be charging its customers to upgrade to the new OS, for which they previously would have had to pay. Obviously if buying a new computer or any Apple device, you'll get the OS on the device (which means the OS cost is built into the cost of the computer).
Seems like a good move on Apple's part. Many other news websites today covered this new free upgrade policy; it's not so important here on EE Times but it is an interesting move that should make customers happy.
This super-thin and light iPad and iPad Mini with their super hi-rez displays should prove very popular among Apple devotees, even at their premium price, and the free iLife and iWorks just sweeten the pot.
I don't understand the statement about "larger Retina screen" because the iPad Air has a 9.7" screen, the same size as the iPad 4. Yes, the iPad mini now has more pixels, but also the same screen size.
