Like it does on the 360 and other systems? I don't have high speed internet and am going to get an Xbox One soon. My buddy said he would update the system for me. I'm going to get the Kinect-less Xbox One. Does it come with the "day one" update already installed?
Nope, they're basically identical to the original sans Kinect. I've heard you can load updates from a flash drive if you don't want to take the whole console to your friend's house. But your best bet would be to just take the console because then you can download all the day one patches for any games you get.
