Android and QNX are both far more advanced tablet operating systems, and its only in the app department that they are lacking in real quality.
Even if Apple dont redesign the UI etc for another 10 years, they still need to implement a true multitasking system. They also need to dump the physical button on the front. Clicking it twice just to switch an app is prehistoric in this day and age. Finger gestures and touch sensetive buttons are the way forward.
Oh, you didn't think we'd let you throw that out and walk away, did you?
Please explain how Android and QNX are more advanced OSs in their tablet incarnations than iOS?
