There's a saying about things that you could and should. Android, being the open platform that it is, has been used and abused for the craziest things imaginable. OK, maybe running PSX or Mac II on Android Wear still tops the insanity list, but running Windows 7 on an ASUS ZenFone 2 smartphone is definitely a close second. Or is it? People have run different operating systems, sometimes even different Android flavors, on a single device for years now. What makes this attempt different, however, is its near native performance.
