Right now I have a factory unlocked iPhone 4 16gb which easily sells for $400 on eBay. So if I wanted I could buy a brand new Nexus with no money loss. I see that the Nexus specs blow the iPhone 4 away but specs don't equal performance when it comes to android. My main concerns are battery life, size, build quality, and no apple features (eg: iMessage). Does anyone own this device that can tell me about your experience with it? Also, is there a store that has display models I can try out?
