Both Xbox and Playstation have some good os features. Xbox OS allows much better multitasking, snaping apps while gaming, skype video, being able to que for a multi player match then going to do something else like watching the You Tube app while waiting for an alert telling you that your match is ready and also being able to be playing a game then powering off the system only to come back and the game is still running sitting right where you left it.
Also the HDMI in is really underated for Xbox One. People just think of TV but you can plug in a cell phone, a chrome cast, a PC or anything that has an HDMI out. I sometimes run my PC to my Xbox One which gives me my PC on the big screen in the living room in full 5.1 surround coming from my speaker system. Its the best form of PC in the living room other then having an actual pc in the living room. My PS4 in running through my Xbox One which gives me alot of the function of the Xbox One while playing the PS4.
Remote Play is something I would like to see on Xbox and Phil has already said that Family Sharing is still coming which sounds way better then Share Play imo. Both systems are great and both have a great OS.
