Flat design has been around for a while. I remember seeing them on phones before iPhone 1, and also on various Linux desktops. People says Microsoft or Google did this first hasn't been around enough.

Personally, I like previous version better.

As for other features, iPhone jailbreaking community should take more credit then Google or others, quick access to wifi and other settings. I remember seeing them on jail broken iPhone way before Android.

I fear for my kids. We try to limit who takes pics, still, we find pics of them online. With Google Glass...this task will become almost impossible.
