I love the iPad...I really do! YouTube videos are obscenely slow, though. I even visited the Genius Bar today. Of course, on Speedtest, my home connection was 1.26 Mbps, and YouTube is just as everyone describes..slow, freezes, never able to play more than 10sec @ a time. At the apple store, YouTube acted perfectly (slight freeze once, but the apple guy just shrugged it off as a buffering hiccup). Speedtest there showed 8+ Mbps, of course. So the guy chalked it up to my slow Internet speed. Sigh.
The problem though, is that with the SAME home connection, I have no prob. Watching Youtube on my Mac mini OR my old pc laptop. I really hope they fix it soon....if anyone has a temporary fix, I'd love to hear it!
