Chrome OS would be missed (at least by me)
My employer (FTSE 100 for which I am the CISO) is likely to roll out Google Desktop (particularly email, calendar, Drive) in the near future so I have been evaluating Chrome OS as part of the future road map.
It takes a bit of getting used to but Chrome OS has some real advantages in terms of OS verification at boot and simple management. I would be very disappointed if it were to be killed off.
Chrome OS use has ramped up slowly but it fits neatly with Google's cloudy strategy. Being able to run Android programs would be useful but killing it off entirely would be a shame.
