I think the new iPads look amazing from a hardware standpoint, but iOS 7 was clearly designed with a stronger emphasis on the iPhone. Many UI elements/features (folders, multitasking, notification center and Siri) and stock apps (Newsstand, Music, Photos, Game Center) don't look like they were properly optimized for the iPad's larger displays. It feels like a blown-up version of the iPhone's version of the OS.
I hope when iOS 8 is announced and previewed at WWDC, it will look more complete and complement the iPad much better than iOS 7 did.
