1. Does a smartphone interact as fast with the xbox as a wii u tablet? (lag issues)
2. There are hundreds different smartphones, you'll get compatibility issues, look at windows... i've had that various times on my pc with the installation of hardware nd software...
3. So this means you gotta use your controller and smartphone at the same time... so i gotta like.. put some ducktape on it and stick it to the controller? No really, that's so handy (*facepalm)
They would combine apple tv with cloud gaming, so it would be cheap and easy to sell. They would never make a console because the console gaming era is reaching its end.
