I had the opportunity to use it for a few weeks at work, when developing and Android app, and made the jump from the iPhone to a Nexus 4. Google Now is incredible. Last week I went to another city for a family funeral and the next day it was showing traffic to the place I slept, sights to see, etc. This weekend I was walking around town and a card showed up with movie times. It's little things that wow you and actually turn out to be useful.

The Android experience is very good now, but I would be lying if I said that app quality is nearly as high, especially in things like photography and audio. That still makes me think about whether my commitment is long-term.
