I would assume google uses Android to just help get onboard chromeos (example: netflix app etc). You want android devs to handle the outside chrome. No thanks. Whether it is A11 or not a large majority does not care. It is only power enthusiasts that need latest A13 in chromebook. For the rest, not at all.

See they are learning a lesson from iOS. Keep tight control - at whatever cost. The same complaints about file management is there in iPad but devs have no option.
