As somebody who does a lot of web-oriented work, what weighs me down the most (in terms of development environments) is the need to test my sites on multiple browsers and operating systems. I suspect a lot of developers are in the same boat.
At a bare minimum, unless you're targeting a very specific audience, you need a couple of virtual machines running Windows so you can test in IE, and ideally a way to run Safari as well.
Of course, you could keep it thin and have an instance running those virtual machines up in the cloud somewhere, and VNC (or whatever) into it with your Chromebook.
Wow, thanks. I hadn't realized how far services like that had advanced.
Browserling lets you run an interactive session (not just screenshots) and will SSH tunnel so you can test sites on your local machine/network that aren't publicly net-accessible. Neat!
