The Switch obviously. Betting on ARM technology way before Apple did it and which will be the main architecture for PC to come was very forward-thinking. Taking the great technology NVidia created with the Shield (but which is stuck with Android) and giving it a full great public exposure to let it have its moment to shine was a great move. And giving it a developper-friendly internal design, pishing the whole gaming experience to the farest they could possibly can and collecting great success with a huge variety of games is just insane.
