For me it is quite awesome to be able to play a game on my PC, and take the Deck with me and continue the game on-the-go, then pick back up on PC, without losing progress. It’s pretty seamless.

Also, if I’m just downstairs from my PC, or outside, I can stream from PC to Deck and enjoy reduced battery consumption and faster loading times. I think the graphics look much better too, but that may be optimistic-colored shades.
