If you take the UK as an example, a lot of the country (outside major cities and metropolitan areas) is still stuck on 512kbit. The same is true worldwide with even parts of SA on dialup. Shouldn't we be concentrating on throwing more resources into getting these connections usable rather than feeding crazy large bandwidth to the rich?
As the broadband speeds are controlled pretty much by consumer demand, isn't it better to have more people than an elite few?
On the same subject, I'm sitting here on approximately 12Mbits and I genuinely have no problems with it streaming HD iPlayer and with three computers on it. I don't need any faster and it costs a whopping $20 a month equiv (unmetered consumption).
Also, if you consider the cost of bandwidth and caps thrown on people in Europe, a gig connection would suck up your entire allocation in about 48 seconds...
