It’s hard to pinpoint one thing. The whole thing feels snappier. Plus, the 90hz is awesome, the trackpads feel so much better, I love the redesigned thumb sticks too. Oh, and I don’t hear this being talked about but the touch screen is soooo much more responsive and faster, it’s a joy to use.

As others have said, I thought the same with mine. It took forever to boot up. Had to hold the power button down for a long time.
