Yeah, I'm a big Apple fanboy so I downloaded the new version as soon as I got home.
I think the reason for the slower downloads was for two reasons:
1) as was said, larger files...640 x 480 now on all TV shows, music videos, and movies (up from 320 x 240...4 times better resolution)
2) lots of people probably downloading the new software, new shows, movies, etc.
I think the best announcement yesterday was the upcoming product referred to as iTV (it will have a different name). Basically, a small appliance that you connect to your TV which will allow you to wirelessly stream music, photos, TV shows, movies, etc. from your PC to your TV.
