I have had an Iphone for the last 2 years ago. Reason why I went with the Iphone, was mostly because I had an ipod touch, I was tired of having two similar devices all the time. I had a Nexus phone, but then I had my Ipod touch. I had to charge two devices. When a call came in, I couldn't hear a lot of them, because I had my headphones blasting, and couldn't hear the phone. So then I would blast headphones lower, being afraid of missing calls.
Also when driving, I had to lower the volume on the ipod touch, and then pick up the the phone. The Iphone was the only one, that I could do both at the same time. So I switch to 128 GB, and sold both Ipod touch and Nexus phone.
I like the Iphone, but I do sometimes get the itch to try Android.
But I'm too dependent on my itunes, I don't really like streaming, I have wasted too much time setting up my own library.
So I don't see myself sampling an Android any time soon, though my mom recently got an Iphone, she is having a hard time, she liked her Samsung phone better, is because Phone App, was way more advanced in Samsung.
Apple really has a horrible Phone App. When you do compared it to Android's phone app.
