Often feels like I'm reading a document, not looking at an application UI.
Surprised to see texture in Notes and Reminders.
Non-flat app icons really stand out (badly).
iBooks, iTunes U, Find Friends, Trailers — all Apple apps whose icons don't yet appear to have been updated.
The new compass app is actually my favourite. Not that I ever used the old one.
I didn't expect to still see the old keyboard but I guess it still crops up in some apps that haven't updated. Today I saw it in the Trello app.
