I very much doubt this is going to be the case.
From a system perspective, smartphone is a Tool. Though it is salient to users (just like the light bulb), the main bottleneck in system growth is Distribution (communications infrastructure.) Another critical element is the Source (cloud computing.) Today, the real innovation requires massive investment in 4G networks, data centers, and content provisioning. And don't forget about all the security holes in the existing mobile architecture, which prevents a large scale adoption of the technology in the enterprise market. Patent battles between smartphone manufacturers make great headlines, but they are largely irrelevant to the big picture.
