why doesn't the ipod touch/iphone have....

... the ability to download youtube vidoes? i just find it a pain that you have to be connected to wifi just to watch the vids, when you could just copy them to the 8/16gb that the ipod has to offer. hope they add a feature like this with a future update.

I don't have to connect my iphone to wifi to watch vids. Never have.seeddrmmr

Is it using the cell phone internet service that comes with unlimited use with the required AT&T plan when you play them? I figured it was too slow of a connection for youtube without using full broadband internet trhough wifi.
