I'd rather have my own "archive" and manage the data bits as I see fit.
I don't like to be nickel and dimed or to have my download viewing habits monitored for "ratings" guides.
I kinda like doing things that way.
I use 'pay per view' and 'movies on demand' on cable quite a bit.
That way, I don't have to go out and find what I want to see. I'm crazy busy, I get to a store like twice a year. I try to remember to buy stuff online, but I tend to waste too much time freeping and playing Civ :-).
It works for me. Well, that and my TIVO -- I couldn't live without that!
