Very early days but here are a few more of my thoughts on the Pixel 8 Pro:
Battery life hasn't been getting me through the day so far (that may change when it settles in)
There is a lot of processing with the camera which I find to be a bit of a pain, hit the button to take a picture and you have to wait upwards of 10 seconds before the picture is ready, as we little notice comes up at the bottom left saying "processing" I find that to be very annoying, especially if wanting to take another picture quickly.
Not being able to remove the Google search bar from the bottom of the screen is not good, I never use it.
The UI is very fluid and fast, except for in some apps which seems to lag by a second or two, not all the while but it does happen.
Those my thoughts, but as I said it's early days (Day 3) things could change. The big one for me is battery life, that MUST change or it will go back. I have to be able to get through a working day with battery life.
