This is honestly a valid critique. While many push flat or semi-flat as the successor of skeuomorphic/textured design (in terms of looks and use), I think in many ways it doesn't provide a completely better experience. An example for myself: it took me several minutes on the (flat) Google Maps app to figure out I could pull up the bottom card to do Street-View. Good luck non tech-savvy people!

These comments about the older generation dealing with flat design are also VERY valid. Apple hasn't gone too far into Metro territory, but it will be interesting to see how the useability end of iOS 7 goes over (never mind the criticisms of the look).

Either way, I think Apple needs to polish what they showed at WWDC. Let's start with the arrow pointing up on the lock screen lol.
