I pay $60 a month for 23 gigabytes of 4G on Virgin Mobile - it's almost impossible for me to use it, and I avoid work wi-fi and casually watch video. A year or so ago, I got 8 gigabytes for that $60.

Admittedly, Virgin is a bit of a value leader, but the world is headed toward extremely cheap data, so it's savvy for a startup to make a product geared toward that.
