Windows/Mac/Linux: The official, actually-made-by-Google Chrome OS won't hit netbooks until late 2010, but you can try out a custom-built Linux distribution that's somewhat stripped down and puts Google's browser at the center of everything.
"Chrome OS" was built using SUSE Studio, a distribution and virtual appliance builder spawned from the OpenSUSE Linux distribution. It loads up with a Chrome icon, uses built-in webapp links to Google Calendar, Gmail, and other Google services as apps, and carries a copy of OpenOffice, just in case you need some straight-up desktop editing done. Most importantly, it holds the latest development copy of Google Chrome inside, along with a pre-built Flash plug-in.
