I would also not like any constant widget at the top of the screen, but if they refuse to remove it, I like how it's done now. I like the fact that it's only on the home screen now, vs. being on every screen , like the old Google search bar.
I wanted to update my experience with this widget. It seems to update better when restarting the phone now. Whenever I restart, which is rare; I only have to refresh the weather or just wait, and it will switch from the clock to the weather. It's still a little inconsistent for my liking but it's better.
