Chairmen Gruber, in a conversation on Tweetbot:

In a sense, then, perhaps there is something droid-like about the Android user experience. Not in the artistic, warm, humanist way that the Tapbots aesthetic is bot-like, but in the cool, rational, science-not-art, thinking-as-opposed-to-feeling sense of artificial intelligence. The difference between iOS and Android, design-wise, can be summed in a single word: magic. iOS aims for it. Android doesn’t want it.
