At the time shortcuts and start menu were true innovation to the GUI. Everyone copied that(a true sign of innovation). However take the last 15 years and no true innovations. Even people rave about the Surface keyboard don't seem to realize that they simply took Apple's innovation(Smart Cover for iPad) and extended by adding a keyboard. Cortana is just a mash-up of Siri & Google Now. Heck Windows Phone 8.1 doesn't even have gapless audio playback. Apparently a deficiency in the OS audio engine... Very sad state of affairs. I would think MS has a lot of talented software engineers, but no real visionary like Ive.
