Comprehensive Chromebook developer setup guide

I've been using an HP Chromebook 14 for about a week as a development (and personal) machine, and so far I'm pretty happy with it. I keep meaning to write something up, but this post is a good starting point. I went with crouton (option 3) and for someone like me who uses a browser and a terminal, this is a great way to go for the price.

You might add a 3.5: crouton without running a full X/Ubuntu setup and just using 'enter-chroot' (instead of startunity/startxfce) paired with the Crosh Window Chrome app gives you the ability to have terminals open without running a full separate X instance to switch between. This is what I've been doing for the most part. The Chromebook's full screen toggle button and alt-tabbing makes switching between terminals and the browser really fast as well.
