It doesn't have one-click, instant billing to 150 million subscribers... so that's kind of a big missing piece, there. In the same way, a horse-drawn carriage has some of the good features of a 2011 Mercedes-Benz SL65 AMG Coupe, like wheels, the freedom to move faster than walking without using much physical energy, and a storage compartment. It also has none of the environmental downfalls. But, you know, it's kind of missing the internal combustion engine.
