Hmm.. I will avoid jumping into the OSX vs Win debate, for my own sanity. Win10 is pretty awesome - I was always a big fan of the start screen covering the whole screen, so I am glad they kept the option to have that in. My biggest issue with it however, is the way they have yet again redone where all the settings are - I wish everything was back in the control panel or the new redesigned box, instead of things appearing twice in some cases, or in one or the other. It becomes a little frustrating at times. The general aesthetics of it as a whole, are a lot more pleasant too, which is a plus.
