Didn't want to hyjack the WinOS thread so... Has anyone tried ChromeOS? Hexxeh is making builds for running off USB keys and there is also an option to install, wipes the drive btw. All the details can be found here; Chromium OS builds by Hexxeh After making the recovery USB disk and imaging my W7 drive to an external drive I thought, why not install ChromeOS. After initially testing it out on a USB key I had nothing to lose by installing it to the hard drive. Everything gets wiped if you do this so take the necessary precautions and backup everything you want to keep. So far it is a very interesting experience. ChromeOS is a browser interface and that is pretty much it (from what I have seen so far) You have a single, Chrome browser with tabs as per normal. Plug in a USB key and a tab opens, open file manager and another tab opens, etc. There is no Start button or Menu, File, Edit, etc. Everything is linked to your Google account so its in the "cloud" (lets find a new name please!) Anyway, I uploaded some files; .doc and .pdf which get viewed in a new tab. Not sure if I'll continue with it, maybe for the next few days to give it a chance. One thing it is is very fast. Definitely recommend it for a USB test drive if nothing else.
