Indeed. iPhone 4's design was a big surprise. The iPad also has very sharp edges (and not so rounded corners).
They're still playing the rounded card with the Touch though, it seems. But I couldn't care less what they do with the Touch; I care only about their iPhone/iPad lineup.
That said, I really hope the iPhone 5 will have the same design as the 4. I hate getting the phone only for the accessories to all be useless in a few months because a new phone came out and everybody jumped on the bandwagon.
