Smartphone shipments outpaced PC and tablet-PC shipments in 2011 according to research cited in a Forbes article published yesterday.

The article caught my eye because I think that smartphones are going to dominate the post-PC era (and not tablets). I can easily see a point not so far in the future where everyone is carrying the equivalent of a laptop in their pockets at all times via their smartphones.

Furthermore, I think that with the help of docks and a blended OS (like what Windows 8 and Windows Phone 8 is turning into), you’ll be able to do most of the production and consumption activities that you currently do on a laptop on your smartphone.

Basically, you’d run mobile apps on the phone when you are on the go but be able to run traditional apps (like Excel) off of your phone when you are docked.
