Market moving towards 5"-7" Phones and 10"-14" PC HYBRIDs
Tablets as a standalone form factor will be going away. Each person will own a large phone and a PC hybrid (with detachable tablet) for work. In the future, its possible that flexible screens will allow for clamshell designs that will flip open for even larger screens. Of course far into the future, we are looking at having phones that have the full computing powers of today's PC. This is why Intel will always be around with their position in PCs and tremendous process lead. You can only make phones more powerful by squeezing in more and more transistors into it.
