Been playing Valhalla on Series X and the console doesn't get overly hot. Basically back of the PS4 Pro hot but without the loud fan. Seems like there was some concern here previously. Maybe it is real concern with faulty units? Not sure. Console is better looking in person. Has a high quality look to it, particularly standing up and the green on top with the mesh. Nice touch. Having a very familiar UI is as reassuring as it is dull. Unboxing was really meant to be an experience here. I can't really savor that but it was pleasant and didn't have any unnecessary annoyances. I always keep the box anyway for storage/moving, etc.
Lgging in and software set up was a breeze. It did take time do to updates, but I had other stuff to do anyways so I never ended up "waiting" for anything. Set up with new controller went really smooth. The new controller I like the texture, but it feels smaller than the old one? Not sure if that's just me or what but I would prefer a larger one. D-pad is clicky, which feels pretty good.
Almost forgot to mention the SSD which is just so nice to not have to wait for long loads, particularly with AC games where you often end up in menus, maps, etc.
