Ok, so you're probably going: "why would you put a phone OS on a PC, why not just go with a 'real' OS"
I'm sure there are several reasons, but I quite like the idea what this would do for the OSes of phones, if people start using it on laptops they will at some point demand the same or similar software/performance of a genuine OS as much is possible, which I hope will be a big boost for the development of the OS which will benefit the phone OS since it will have more software ported to the OS/phone which will make phones even more like second computers.
