Pros
Pro Great media experience
Other than small black bars when watching videos (the 16:10 ratio is close, but not quite the same as most 16:9 media), the media experience is great. Dual stereo speakers facing you help immerse you in what you're watching. At under a pound, you'll be able to hold it comfortably and watch movies for a while too.
Pro Game streaming service available
3 months of nVidia GeForce Now are included with the Shield Tablet K1, and after that it costs $8/month. Games are streamed from from nVidia's servers, and include over 50 titles ranging from Sonic to Batman, Dead Island and Ultra Street Fighter.
You'll need a fast internet connection, and the server might boot you if you are inactive for more than 10 minutes. The games on GeForce are completely separate from any games you already on on PC - for example if you had Sonic already installed on your PC, you couldn't continue the save file on your tablet - you'd start at the start again. You also can't play GeForce games on the PC.
Pro Excellent power optimization
The built-in power optimization is excellent. With a quick toggle in the settings, you can max out settings for media consumption, reduce performance to minimum (including clock speed and number of cores), strike a fair balance, or set an auto-switch based on battery %. If that's not enough, customization lets you find your perfect happy-medium, with stability issues ranging from few to none.
