Ubuntu doesn't make an OS. The put their sticker on, just like how your local dealer doesn't make cars. Also, what does it mean integrate it to work perfectly? Don't say "like osx", because Apple makes the hardware and they make the OS, they aren't integrating them so much as building a single product from those pieces (hardware and software)
