I've recently been playing with a Galaxy Note 2. If your looking for a device that can straddle both the smart phone and a tablet. This might be the one for you.
It's BIG. large screen and it allows multi tasking for some apps. that means you can have a video playing and take notes at the same time, or have a document open and type comments, notes also.
I know it's carried by both Verizon and AT&T. So if it's time for a change, give this one a look. I've got to much $$ invested in IOS apps but got one for wife. It's a fun toy and a usefull productivity device.
