The SHIELD wireless controller uses a custom Wi-Fi Direct solution that offers incredibly LOW latency and superior performance compared to standard Bluetooth controllers. With support for up to four controllers and a ton of serious gaming per charge, the SHIELD wireless controller delivers all the gameplay you can handle.

SHIELD wireless controller brings voice commands and search to your game controller. Use the integrated microphone to search without typing, ask questions and get answers, open apps, and play songs and movies.

It would be cool to have this because you can take it anywhere. It is big so it would take up space so people might not want it.

A vibrant 5-inch LCD TABLET display makes text, colors, and images look sharp at every angle in all your favorite apps, games, and movies.

GAMEPAD MAPPER
Gamepad mapper allows you to add gamepad support to native touch Android games, so you can play thousands of games using SHIELD console-grade controller. Use NVIDIA's default game profiles, or create your own!

 I think that an old person could use that because it is easy to use, from what I have heard. I would want it because I would love to play minecraft on it. I would not like the size of it because it is really big. You would have to use two hands to hold it, it would take up a lot of batteries or electricity. It might be too bright or too heavy.
