Steve Jobs Called Google's Vic Gundotra on a Sunday About this Icon
Here's the thing. IMO, it's a designer's job to think about all the little things. Few will notice them and even fewer will appreciate them. Apple has, in the past, been known for this type of mentality. Now it seems they've given up.
The springboard is the single most important thing on an iOS device. The icon is the first impression a user has to an app. What bothers me the most is how iOS 7 seems so anti-skeuomorphism (to a stupid degree) and yet, we have textures in the Remider and Notes app.
