The iPad 2 will probably have a similar design to the iPhone 4.
However, unfortunately, I think that apple will introduce a few great features in the iPhone 5 and a design change like, touch sensors at the back. And then, the few month old iPad wont have *touch sensitive back.*
Like the gyro.
Disagree. The 4 was the big design refresh. The 5 will bump the specs, maybe add some new peripheral features (NFC, that sort of thing).
