The Post-PC era is a market trend observed during the late 2000s and early 2010s involving a decline in the sales of personal computers in favor of post-PC devices; which include mobile devices such as smartphones and tablet computers as well as other mobile computers such as wearable and ubiquitous ones. These devices emphasize portability and connectivity, including the use of cloud-based services, more focused "apps" to perform tasks, and the ability to synchronize information between multiple devices seamlessly.
