* CPU speed will get vastly more ridiculous, but battery life probably won't improve significantly (on x86 laptops).

* ARM will have around 50% market share as tablets become ubiquitous and laptops move to ARM. Those laptops will run some form of Windows, but Windows will continue to sell poorly on tablets.

* Reliable, reasonably fast internet will be available to almost all of the US.

* Cloud computing still won't be fully adopted. More computer users will do most of their work in a browser, but smartphones and tablets will still run many apps locally and desktop OSs will still be structured similarly to today's.

* Something huge and crazy will happen to education and Khan Academy will be involved in it.
