Are people getting interested in realistic design again? These days everything is flat and boring. Bring back the buttons with reflections!
Skeuomorphism brings to mind iOS design from 10 years ago. It wasn't good looking at all. (Granted, it was overblown and in your face.)
I'd like a retro look with subtle 3D cues, like how Windows and MacOS used to look ~20 years ago. Transparency used in some places (like Windows 7) would be welcome.
