Well, I am having a weird problem watching youtube, and I am not sure if this is just flash being flash or my hardware being faulty. But every once in the while, when I watch youtube, the video and audio get really choppy. I could refresh but it still does the same. On average, I would say it happens once every 30 or 40 videos. Do any of you have the same issue? Mine is the latest MBA refreshed in mid-2011. Hope that helps.
