I'm with you on this one.Why do people have 2 and 3 phones? I don't get it...
I was combing through youtube looking at videos about the note 4 before mine finally arrived.
I stumbled upon a guy who actually CARRIES at least 2 phones at all times. That's what I don't get. I've got my gnex and my girlfriend's s3 in a drawer for backup in case we have to send one in to get a replacement or something, but I can't see spending money on 2 brand new phones at one time just to have one of them sit and collect dust for over half the time.
I think it'd be more hassle than it's worth to set them both up, then, as you use one more often, you start to tweak where things are and what apps are on it and get lost when you go to the other one.
