That's what happens when you decide to use a companies proprietary software instead of vendor-neutral products. If you had an Android, why couldn't you just use Skype or Hangouts? Those are available on iOS and do the exact same thing as facetime.Its very difficult for me to have an Android device as a primary device. Not being have to use iMessage, Facetime and the iTunes is very challenging for me...especially Facetime. Everyone I know has an iPhone and missing those iMessage group chats and Facetime calls (on the fly) are huge deal breakers for me. Just the other day, I was able to view some of a family member wedding on Facetime as it was happening. Unfortunately, I was unable to make it (was trying to rush to the airport), but it was nice to have been able to experience some of it. If, I had my Android device, and left my iPhone, I would have missed it.
What about iTunes can you not do on your Android? You can have your iTunes playlist synced with Google, and access those songs and playlists on your phone or even a computer via the web interface without ever having to plug them in to sync.
Really, people complain about Android but they never even looked at how Android can offer an alternative.
