Yes get one !! Its alot different from the Xbox 360 but everyone is going to have to except some change in there life sometime ! The gaming is unreal on it, so much better than the 360 !

If you play your xbox 360 or what ever console a lot, and you want to get some of the next gen games, then I would say go for it.

Just be aware that every game you buy will cost you an extra 70$ or so as they are all brand new.

Xbox One is great, but the Kinect isn't worth the extra $100,

It's really good, well in my opinion I have been on xbox since the original one previously PS2/PS1 but I enjoy this controller the most out of any I have used. My only downside is the Snap Menus as they are a pain to open/close without the kinect (if you're not using it) but other then that I love it + the ability to record with Twitch or 5 minutes of any game. The voice audio is spot on also. It is worth it.

Honestly, with all the new games that'll be slowly coming out for the One, I prefer XB1 over 360 although I still have my 360 but use it rarely unless I want to play GTA5.
Take a look at the buying guide sticky in the general gamings forum.
