Justin Williams:

What we see today isn’t what we’ll see six months from now. Everyone is still learning to speak the modern iOS design language: Apple included. The folks in Cupertino built a completely new foundation for their mobile operating system in just a few months and are still working out how to best adapt their applications to speak the new language that foundation affords. It should be no surprise that many of Apple’s apps that are distributed through the App Store aren’t updated to take advantage of iOS 7 to its fullest. They’re trying to find the answers to the same questions designers outside of Cupertino are.

A great response to a shortsighted observation by Topolsky. iOS 7 – as also confirmed by Matthew Panzarino’s interviews with developers such as the NYT team and Evernote – will make conversions to Android extremely difficult and unlikely (unless you want to end up with poor interface decisions on both platforms, which is another problem).
