However, in my opinion, not all UIs are created equally. While Sense has its fans and Touchwiz is generally not so invasive, MotoBlur is a flaming, intrusive pile of garbage, every time I use it.
I'm actually quite excited to see what Touchwiz and Sense bring to Android Ice Cream Sandwich, but also a bit wary as well. If I don't like what I see, though, I'm comforted by the fact that I can root the phone and install Cyanogen Mod to get it lookin' good.
What are your favorite – and least favorite – Android UIs? Does the sprinkles analogy work for you or do they just make the ice cream sandwich on the right look even tastier?
