This ChromeOS thing has been bugging me.
Wonder if the following would be a good use for it:
When you are browsing the net and worried about viruses and worms, might you want to create a ChromeOS virtual machine and browse in that? Any viruses however well written, are unlikely to get onto your host OS (to do so, they will have to break the Chrome browser, the Chrome OS, the Virtual Machine software and *then* your host OS.
Won't save you if you are trying to download applications for your host OS. Or from phishing attacks, but should protect you from other threats on the web.
Could that be the killer app for ChromeOS?
