YouTube finally made the switch to HD. Now, when you’re watching videos on YouTube, on some you will notice a little link under the video that says “Watch in HD.” After you click that link, if the person who made the video really uploaded the video in HD you will notice a significant difference in the picture quality. There are speculations that the video is not truly HD (720p / 1080i / 1080p) but the resulting video definitely looks a lot better than the normal quality. Here is the same video, the first is the video playing in normal quality and the second in HD.
