The S4 is definitely going to be interesting. If the batteries are in the bands, I wonder how much more of a mAh capacity it can hold. Looks promising for LTE use. And if a finger sensor is true, that's so much better than a pin.
Obviously the bands will be proprietary which is a downside. But an upside can possibly be, 3rd party bands with extended batteries.
