> I'm an iphone 5s user and was eagerly awaiting the new Nexus to make the switch to Android
I highly recommend that you borrow an Android phone from a friend before making the switch and spending some time with it.
Also, check the permissions on most of the apps on Google Play[1] (scroll down and click view permissions) and ask yourself if they're justified[2].
Once an app is installed there's no controlling of the individual permissions. You do not get prompts asking you to authorize an app to access your contacts, location etc. It's an all or nothing approach.
Some people will tell you to root/flash the phone and install an app to allow you to do what should have been a default OS behavior.
I switched from Android to iOS about 2 years ago, and will never go back until Google fixes up the permissions system.
