Google Chrome OS Operating System

So I've been thinking about changing my operating system to Chrome OS. From what I've found from the youtube videos it's meant to get you on the net fast! Good so far! It seems slick and cool but my question are: Will my printer work on it? What hardware will it support? What is it based on? it looks suspiciously Linux like, as I can't seem to find any offical evidence then my second guess would be BSD which is not a bad choice just look at what OSX has become.
