With the One X, I would leave the console running for hours, even if I was done playing games on it and I was watching a film or something. Then, hours later, I’d return to doing stuff on the One X.
With Series X, I’m actually turning off the console when I’m not using a lot more - I think its because the thing boots up so quickly, and with Quick Resume, I can boot up and get right into games like Gears Tactics in less than a minute, which I think (for me) justifies the decision to turn the thing off more often.
…or is it just me thinking this way?
