Re: Well... Imagine a service that streams Blu-Ray 1080p videos. If the bandwidth is there, the demand will form, and the service will come to exist.
What about Steam users, who download their games?
Or what about the entire system of online distribution of software?
Microsoft has already announced the availability to download games through their online service.
What happens when the PS3 does the same? Some of these games require dual-layer Blu-ray discs. We're talking up to 50 GB files *per game*.
So yes, there are and *will be* reasons to download more. In fact, reasons that neither I, nor you nor anyone else can think of. It's called *innovation*.
