Chromixium OS (http://chromixium.org/
) is probably one odd beast as its basically Ubuntu in Chrome OS's clothes. If this gets developed further, this could be an OS for that someone that finds the Web is all they need. It would also allow non Chrome OS PCs to get the same interface, since Chrome OS devices are unavailable officially where I am at.
Just remember its still rough
1. No auto updates.
2. System account unrelated Google account
3. The usual 1.0 release QC and hardware compatibility issues, that seem to stem from the deviation of normal settings on the Ubuntu OS core.
