Do you have bandwidth to spare? Download some cool movie-trailers (direct-download links in parentheses):
- Mission Impossible 2 (18MB)
- Dinosaur (21MB)
- X-Men (11MB)

This Japanese site has a bunch of X-Box photos and three movies for download. I like the butterfly demo (9MB).

There's also a new Thief 2 movie (11MB).

The Corporate Downloads page at microsoft.com is a handy alternative to Windows Update. Unfortunately, it still doesn't offer direct-download links (that Getright might catch).
