Just watched. The announcements were:

  iOS: customize home screen + control center
  apps: floating tab bar menus
  apple apps: animations + doc browser
  screen sharing: pencil annotations 
  calculator: math notes + brett victor animations
  apple notes: handwriting digital twin

Cute features, sadly of low benefit to work use cases. High value would be a VM and CLI terminal to run a web server stack for offline dev, maintenance or publishing tasks in time and space constrained contexts where Macbook would be inconvenient. Macbook is good for hours of dedicated work, iPad for quick tasks.
