The Nvidia Shield Portable is an all in one portable Android gaming device.
Con Navigating is cumbersome
Users can use the dual analog sticks to maneuver around the OS but sadly t is time consuming and not as accurate as touch controls. Users can of course use touch controls but now holding the device is difficult due to how it was designed to be held, with two hands.
Con A relatively small subset of Android games available are optimized for controller use
Out of the majority of games available for Android most only have touch controls. There are a few that utilize HID controls and even fewer that utilize the nVidia controller. This makes for a very limited selection of native games to play on the device.
