Comfortable gamepad with powerful Gamepad Mapper feature. Excellent build quality. Very fast for an Android device. Lots of connection and storage options. Local PC game streaming works well.
Expensive for a gaming handheld. PC game streaming is unreliable outside of home networks and requires specific GeForce hardware.
The Nvidia Shield Portable is one of the most unique Android devices out there, combining a 5-inch tablet with physical game controls.
