Smartphones have a very narrow range of OSes you can install, and it's extremely difficult to install them.

PCs have a wide range of OSes you can install, and it's relatively easy to install them. PCs can also use mobile internet connections through cellular modems.

Given this situation, would it be viable to switch to a pocket-sized PC instead of a smartphone? What is holding back pocket PCs?
