Weather app in iPad is great. I've always disliked not having apps across all devices Home screen exactly the same on iPhone and iPad. Though I guess that will be harder as iPadOS continues diverging from iOS.

Stage Manager on iPad is actually very cool. On macOS we already had multiple windows and Spaces and now we're getting the equivalent on iPad and it'll be interesting to see if it works with all apps (a lot of system-wide features that you think would be automatic have to be supported by apps, even if it's just setting an internal preference or doing an API initialization call).
