Not only does the wallpaper take forever to change, there is absolutely NO feedback. There is NO response to any of the button pushes. (To save for home screen, lock screen, or both.)
Not sure if intentional or not, but there seems to be a disturbing trends toward NO feedback for buttons presses, relying, instead, on the action that has been requested to be performed.
So, you press a button to save wallpaper, the "feedback" is that the wallpaper has changed. But you don't see anything change. (Maybe on some unreleased iPad
) You just have to "cancel", and then sometimes the wallpaper has changed, and sometimes it is not.
All the wallpaper hurts my eyes, anyway.
I am very disappointed by the design. It is NOT pretty. It is NOT well-designed. It is NOT harmonious. It is ugly as sin. The thin fonts are hard to read. It seems change for change-sake, and, really, just new skewmorphisms. My screen is not 3D. It's a flat damn screen. Draw some flat damn images, not fake 3D backgrounds that eat CPU!
Man, are the group icons ugly, but I read that has something to do with transparency support, and won't be as ugly on iPhone 5.
Overall, seems sluggish especially with respect to touch input - poor feedback. And the effects are mind-bogglingly meaningless. It is just gratuitous flash. Why do icons have to fly from all over the place? Why do page changes (may just be specific apps, though, such as Zite) have to be so bizarre? Why wrap things into weird shapes when you scroll? Is there some purpose to any of this?
