I have been using the device full time for over a week now. I understand a couple bugs but I do not have the issues (anymore) that most people seem to be commenting on.
Yes I had some challenges with the device but once I got to understand that with two completely separate accelerometers, orientation when you fold the device is important to get the reaction you want. Hold it more in an upright position when you fold it and the proper screen will show.
Also the gestures are a little bit more finicky than my pixel 4 was. Examples, where you put your finger to start the upward swipe for the app drawer is critical, and when closing an app you swipe up but if you swipe slightly to the side, it will flip the app to the other screen. So the main bug here is the precision required for swiping is a lot more than I had with the pixel 4
If you don't fold the device properly and there is active screen on the back side and your fingers are on it for support, it will make the front screen shake wildly. Back to my comment of how to more consistently hold the device to get one screen to show.
I do agree there is some lag or freezing occasionally. To me right now that is a valid bug.
Oh and one of the first things I did was get rid of that Microsoft keyboard and put gboard on.
Am I a fanboy and that's why I'm making positive comments? Heck no. I just like playing with new devices and technology, and finding out how to work through the challenges, instead of expecting absolute perfection right out of the gate for something as complex as this device. It is fascinating to see what we have today compared to what we were playing with in the late 90s.
Am I keeping it? I'm not really sure yet. I'm not a big camera user but the camera does fall short from my expectations, particularly in low light. The lack of wireless charging is a step backwards but not a deal breaker for me. Having to open the device to see notifications is good on one hand because it does not distract me all day long, and I get notifications on my watch that I have prioritized.
The biggest positive of the device? I can consume information much easier now, like this forum

and respond.
