You can download and run Chromium OS today if you know where to find it, but be careful. If you just Google for "chrome OS download," you'll probably end up with a modified version of Suse Linux--the "fake Google Chrome OS." Ironically this will run just fine on most netbooks, but you've got to be a Linux master to use it. You can edit files on the Web with Google Docs, or on the local computer with Open Office (which is included), but you need to keep track of where your documents are saved and manually move them back and forth. You can download and install cool programs from Linux software repositories, but there is always a chance that a program that you download might hack your system and steal your data. And you need to remember to run "software update" on a regular basis to install those security patches. In many ways the experience is quite similar to running Microsoft Windows or MacOS.
