Samsung and Acer will be the first companies to sell the laptops in the UK. They'll cost between £214 and £350.
Battery life is a day, says Google. Boot time is eight seconds.
The big snag with the things is that, being Google, it is optimised for web-based applications. With the spotty state of 3G in the UK - and it's 10X worse in the US - this will be a big obstacle to take-up of these lap-tops.
"Ultimately the most precious resource is the user's time. I think the complexity of managing your computer is really torturing users out there. It is a flawed model and I think Chromebooks are a new model and this is the way things are going to be," says Google co-founder Sergey Brin.
It's funny how these top chaps are completely out of touch with how the rest of us live. Obviously they have access to permanent, cast-iron communications links which never go down. So they think that's the norm.
But for most of us, it's not, and if you can't get a connection, the best laptop is a dead machine.
