Clearly, many people here do not have an Xbox One so they don't get why backwards compatibility is a big deal. There are many great Xbox 360 games that I still like to play, but am so used to how well the Xbox One works - how to can instantly switch between things, pause, TV (watch the high speed chase) check on something, then resume.
Plus many games are to get a graphic and frame rate improvement, plus you get to keep the Xbox One features. The difference between a 6th gen and a 7th are quite a bit different. Many 7th gen games still look pretty good and play well.
This is NOT the same as the WiiU as they DO NOT do a graphic/frame rate upgrade. So when you play an old Wii game on the WiiU you get a screen full of jaggies.
This is a big bonus for the Xbox One.
