I mainly just want a bigger screen. I would use an iPad mini as my phone if it had cellular. I could care less what people think or what I would look like holding it up to my ear. Use the earphones if this is such a problem. Add to the fact that it's got better resolution and features that the iPhone 6 doesn't have.. no brainer.
This.
Couldn't have said it better myself. 6+ all the way.
