I have the Nexus 7 and iPhone 4, upgrade to iPhone 5 or Nexus 5?

Is there even a point of having the Nexus 7 and Nexus 5? Like, does the 7 offer everything the 5 has besides the obvious phone features, making it more worth while to just upgrade to the iPhone 5? I won't really miss the "iPhone exclusive features" such as Facetime and iMessage, though my family wants me to get the iPhone simply for Facetime but in my whole life of having an iPhone I've used facetime a total of 3? Times. I feel a face to face convo could be held through skype, or maybe even the google hangouts app.

I really love my 7 and Google so I feel going full Google/Android and away from the yucky Apple iPhone is the way to go. Your opinions?

Sprint 2-year contract upgrade?

I'm really confused about this whole thing. My 2 years is coming up (in November) and I want to know what will happen? Do I just walk into the store and trade my phone for the new one I want? Will it be free? If not how much? I have a galaxy s3 and I want a 16gb iphone 5c.
