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.

Meh. Absolutely love my SD but got the LeGo due to the big screen and nice ergonomics. I’m probably going to return it though. It’s nice it has a trackpad but it sucks. It’s slow and doesn’t click. The software is a giant mess at this point in time and I hate the sticks. They are small, have little travel, and have HUGE dead zones. Terrible for any FPS but would be ok for casual games. Screen and touch input/responsiveness are incredible though. It has potential but it’s hard to justify the price when I love everything about the SD other than the screen and wish it was a little more powerful.
