I'm still in the middle of installs, but everything in the dash is so much snappier. Hopefully it doesn't bog down for a long while.
System is quiet when idle, but it's a bit noisy during [disc] installation.
The A face button on the controller doesn't seem super responsive. Seems like it needs a really firm press to respond. It's not that problematic as I'll just be using my Elite when I switch that over, but still irksome.
The power light is a mini sun. Could be the difference in age and use, but damn was that bright on startup compared to my OG XBO.
I probably won't play anything on it until I finish Wolfenstein TNO on PS4, but so far I'm impressed with the system itself, and happy to be finally going back to using an XBO controller.
