If you have read the title, then you know that what you are seeing here is the first official Chrome OS device.
Now, you would think that the first Chrome device of its type would be a netbook or notebook, but no, it is a monitor.
This DX241H is made by Acer, who actually partners with Google. According to my Source, there is no reason why they would go around the company to make some sort of all-in-one iMac PC on their own.
From what we heard, the first official Chrome OS will be a notebook, not a monitor or all-in-one PC, and it will launch sometime in the summer of this year.
