I jumped off the Apple wagon from the Ip5 to the Galaxy S4 for a bigger screen, etc. I made a lot of changes to get it to perform like my Ip5. Make no mistake, it's a great phone, but I am getting the Ip5S. I analyzed my usage patterns: I do virtually all my surfing on my retina MBP. I don't game on my portable device or watch videos. So the only thing I really use it for is bluetooth music for my car, email and calls. I'm coming back to a familiar system( had a Ip4 also ). Not a bad thing.
