I don't agree with Steve on this. It could be years before 'the rest of us' have fast, ubiquitous Internet access so support download/streaming services.
We're 8 years away in Aus. That's if everything goes to plan, AND that's only to get fast speeds (100Mbps-1Gbps) - the download limits would mean you would probably only get a few 1080p downloads a month for under $100.
So yeah, probably at least 10 years down under before we can just download a heap of 50GB files willy-nilly.
If only there were some optical disc format that had the capacity for HD video and large file storage, AND was available now...
