The nature of the Steam Controller - intended as a semi-substitute for mouse and keyboard - should mean that it's the most universally flexible controller to use with the app, although it'll be interesting to see just how easily other devices can be paired with the system. Thanks to Steam Input support, you'll also be able to pair Bluetooth game controllers (such as Valve's own Steam controller) to your handheld device, allowing you to play a much wider range of games free from the shackles of touch-screen interfaces. You'll need wi-fi good enough to broadcast a smooth stream, plus a device with enough CPU grunt to decode it without stuttering, but other than that there shouldn't be too many limits to the Steam Link software outside of a few extra milliseconds of input delay.

Today's announcement suggests the idea is very much alive and well at Valve: soon you'll be able to play games from your Steam library through most iOS and Android devices via an official and free Steam Link app. When Valve practically started giving away Steam Link boxes for little more than price-of-postage, I assumed that the company was stepping away from the concept of in-home streamed gaming.
