Very nice! Take that you slow Internet connections. LOL This was the first 4K video I saw on YouTube: 4K is cool and all but we don't even get "Real" HD at 1080P yet via the fastest cable providers. They all are compressing the crap out of the video and pixelation is very visible on a decent modern television. It will be 10 years at least before any of the cable companies up their equipment to handle a real 4K signal. My guess is that the satellite providers like Dish will never be able to deliver a decent 4K signal.
