I am trying to decide what phone I want for t-mobile. I loved my S3, and I've had and loved an S4 (except the battery life) when we were on AT&T. We recently switched to t-mobile and I'm wavering between these three models. The S4 is tried and true, the note looks awesome but I worry if it's too big and cumbersome to tote around in real life in my pocket. I also recently got an ipad, and while I haven't been impressed with iphone or ios 7 lately, I adore my ipad, and I am wondering if it would be easier to have everything together on one OS. Help me make some decisions!
