Got benchmarks on those speeds? You can edit video on a MacBook Pro too.
I paid $200 for 10 inch surface r t. At first I wasn’t impressed because of 8.1 but I have to say it doesn’t glitch up and it does youtube and podcast really well. Also does netflix very well.
I know you can edit video, but did you see the live transitions between video?
And yes an NVIDIA GPU will smoke an intel integrated GPU. If you’re talking just CPU tasks then I’m sure the Surface Book isn’t 2x as fast. But anything that needs heavy GPU use it will be 2x as fast.
