That's one of the reasons I bought today. I thought it gave me just enough time to figure out if I like the iPhone enough to keep it and to get some hands on time with the 920. I don't really care about customization, but strong development is a must.
It would be a hard purchase to make because it's so damn big. As much as I dislike the S3, I'd be more interested in the S3 mini (unless that thread was a joke).
