Did youtube performance ever get fixed?

[newdeal]

I had an ipad I sold awhile back in anticipation of the ipad 2. When I sold it youtube videos were loading FAR more slowly than on my imac on the same wireless network. To the point where the ipad would take 5 minutes to buffer a video and the imac would start playing it right away. Did they ever get this sorted out? Not sure if it was because my imac is doing 360p and the ipad was trying to do a higher quality video or what but the differance is rediculous and I was just wondering if it was fixed so I know what to expect when I get the ipad 2
