The current app pool seems to lack a specific design language, I'm not sure how to put it in words, but it's not cohesive and seems separated. ICS has changed it but only the native apps seem to follow it, and even then I've discovered some inconsistencies in the UI. It lacks a specific identity....I guess that's the payoff for being open and flexible I suppose.
I wish Android used Qt Quick Meego/harmattan components and squircles lol, I wonder if anyone tried to do that
