> Smartphones have been "pocketable PCs" for more than a decade already, but are dumbed down because their inputs and outputs are limited.

I wish it was only about the i/o: pocket Bluetooth keyboards, mice and other i/o devices would be just a few bucks away. No, the problem is rather that phones/tablets use crippled dumbed down and tight closed operating systems that offer only a small fraction of the power a real computer offers, not to mention the huge privacy and security issues involved. Having the same hardware performance and storage of a good laptop means nothing if the OS doesn't offer a way to use it in a transparent and trustworthy way.
