Jon,
I just realized I did not answer how easy it is to hook up to another monitor, so this link describes the process. When I mirrored to the TV the other day it was quite easy.

Roger,
I should add corrections to how I answered your questions, I am not sure about your #2, I do not know for sure. And the chromebook lacks the processing power of a laptop. I defer to the tech gurus on your questions.
