“The smartphone started it, but the Post PC Era will begin in earnest when the functionality that we currently see in the home computer is replaced by numerous small appliance-type devices,” Linux Rants explained. “These tiny Linux PCs are the harbinger of those appliances — small, low-cost, programmable devices that can be made into virtually anything the owner desires.”
The “computer” as a separate device will soon disappear. This will reduce a lot of the anxiety towards technology, because people will no longer be confronted by a big box of puzzles that they have to sort through in order to accomplish their mundane tasks. Rather, the computers will be built into items designed to do certain kinds of tasks; the interface will be more intuitive and less frightening, and probably harder to work around.
