I used "Linux Deploy" for a while and my main gripe with the various Linux-for-Android solutions is I couldn't find a good GUI setup for them. The VNC-based solutions were laggy and didn't work when I tried to scroll or even right-click, and had wierd modes of mouse navigation. Using XServer XSDL worked better but still had random problems at times. Youtube had sound out of sync for instance. Also I really wish there was a GUI solution that could make use of the high-DPI screens of Android devices.

Crouton is working fine for me on a Chromebook though. Although sometimes I wonder if I should have gotten a Zenbook instead of a Chromebook ... the 16GB eMMC is really annoying.
