Refocus is awesome and I owe many but not as powerful as this at all - Refocus takes like 10 photos at different levels of focus, so you're limited to the amount of bokeh that the small phone sensor can produce, i.e you only get a nice blurred background when you're taking a really close up picture of something. The new Google Camera feature lets you take a portrait at a normal distance, and simulate f1.8, which is a lot better than what Refocus can do.
