One thing great about today's announcement of Pro iPad apps: not even a hint of iPhone compatibility.

Universal binaries, and more importantly Universal SKUs, were such a bad idea. Just because the APIs are the same doesn't mean the products and customer base are, too.

If dual iPhone/iPad apps are unsustainable for Apple, imagine how it was for small and medium sized businesses.

@chockenberry seems like a huge leap to conclude that Apple has determined that, in general, universal apps are unsustainable. These two apps, more than any others, require screen real estate in ways that the vast majority of apps do not.
