I’m a Chrome team member and saw this going around Twitter.
Just wanted to say, you can right-click on the Cr-48 by tapping with two fingers (or holding Alt and single clicking).
You can also flip the developer mode switch under the device and get full access to a shell: http://www.chromium.org/poking-around-your-chrome-os-device
hope this resolves some of the comments!
