1.	What if, in the middle of the night, while I'm not using my computer, it downloads huge video and audio stuff to my local hard drive. Then when I arrive in the morning there are fresh bits, news clips, movie trailers, a song of the day, whatever, provided by all kinds of content providers, from big TV networks like CNN and MSNBC, to a Dutch school where kids are taking a film class using inexpensive video recorders and Macs.
2.	Let's see what happens with 1, 2 and 3 in this scenario.
3.	1. When I click on a link to view some video, it starts playing immediately, because it is already on my local disk.
4.	2. The wait is zero.
5.	3. The quality is limited by the size of my local disk, not by the capacity of my connection.
