If anyone has bought an xbox one for themselves/kids xmas word of advice when you initially turn it on does a sizeable 4.2 gb download.
I got mine out of the box to check everything was ok after a big PS3 download at christmas few years ago, glad I did.
Currently at 21% after half an hour, with a reasonable internet connection. Could be here a while...
To avoid abit of christmas upset get the xbox on tonight/tomorrow so when the kids get it it should be relatively plan sailing.
