> After buying a chromebook a month ago I am completely convinced this came a few years ago and no one paid any attention as it wasn't the vision they had of the Linux desktop.

I noticed but I don't think this is a satisfactory Linux Desktop. It goes against many stuff Linux Desktop proponents could be fighting for, mainly privacy and controlling one's computing. The main point of the Chromebook is to make your computer a thin client to run your computing on Google's servers. I think computing should go the opposite way. It's fast and has no virus though.

As for the market share, I know nobody with a Chromebook around me, I don't think it's a big thing where I am.
