It seems like an obvious choice for such services, but there is a big difference between a service being good enough since it is free and being good enough to pay for (if you have to pay there are a lot more alternatives than if you get it for free).<p>Itunes is good enough to pay for, but I can't imagine I am going to want to see an entire movie in flash quality on youtube and pay for it. I will much rather pay for the DVD and get it in a good to great quality.
