Comment ChromeOS + SSH client (Score 1) 99
The Secure Shell extension for Chrome gets you a usable terminal and SSH client. If you need to edit files locally, vim is available too, along with several text editors. There are a couple of git clients floating around if you want to edit stuff with source control.
This isn't such a good option for me. I use LaTeX on my chromebook and want to compile stuff. I want to use sed and awk and wc. I currently use Crouton, though I'm probably going to install Chromixium instead.
