The chromebook runs an operating system specifically designed by google, so no item is going to be perfectly like the chromebook.
If you are just looking for that size, I would look for something like the Asus Vivobook.
Otherwise if you are looking for that size and price, you should probably start researching some **broken link removed**, although the netbooks are not going to be as fast as the chromebook by a long shot.
Chromebooks are garbage. The do not support java since google and java have problems with each other so many sites you cant even get on because they use java.
