There's a chrome extension by Google that provides a supported way to ssh on ChromeOS, from the device. There's limited support for SSH keys built in, and there's also a mosh extension.

(It's pretty easy to enable developer mode in order to allow unsigned code to run, and then Ubuntu/other Linux can run it in a chroot, though education/corporate deployments can/should prohibit that by policy, so isn't relevant to the larger discussion, though it means personal ChromeOS laptops can be quite functional.)

It has a built in terminal called crosh, which might have an SSH client built in (I'm not sure). What most people do is download a chrome extension like Secure Shell[1] that lets you ssh from a tab.

Me neither, but this looks interesting:

I might pick one up at Fry's today just for giggles.

Update: Tried to run the NaCl Development Environment on my macbook to get a taste and it just crashes on launch. Seems like a lot of people have the same problem on chromebooks too: https://chrome.google.com/webstore/detail/nacl-development-e...

So maybe I'm not so excited to run out and buy a chromebook for development just yet.

There's an ssh client in the chrome store($0, I think it's published by google). It runs as a chrome tab (one tab per connection), which means you do waste some screen space for browser UI that doesn't make sense, but it's workable.
