Try Chromium OS

If you don't know already, Chromium OS is Google's effort to remove the operating system stage in getting you to the internet. To do this, they have turned the Chromium browser (Google Chrome is based on it) into an operating system. This means you boot directly into your browser without any need for your operating system (Windows, Ubuntu, Mac OS) to load itself up. This also reduces the risk of viruses because you are running a browser and not a full operating system with customization. To try it out, you can purchase Chrome OS Hardware, or you can try it on your own hardware. Option one would be to use a USB, and option two is to use a Virtual Machine within your current computer.
