No one in the US wants to watch 480 video.
Of course, what I would -prefer- is to ditch Comcast, and yes, watch at a higher resolution, and I will at the first available opportunity. But can't. Because monopoly.

480P looks surprisingly good on iTunes. Much better than DVD typically. I'm OK with that for the most part.
OTOH Netflix's auto-scaling is clearly the future.
My 5mbps AT&T DSL struggles to load Hulu and Netflix on a daily basis, even at just 480p
