I just realised, in Japan where bandwidth is cheap and unlimited, the thought is never on your mind that you have to try to get your money's worth. You pay a reasonable, flat rate per month, and as such you don't feel compelled to try and squeeze every last MB out of your monthly plan.
Here is Aus, where bandwidth is expensive, and limited, we employ bandwidth throttling in out bittorrent clients, and install dahsboard widgets that meter our usage down to the MB to make sure we don't get speed throttled, or let any of our precious, pre-paid MBs go to waste.
And come to think of it, I don't think I've ever download more stuff in my life. I mean just yesterday was the last day of our billing cycle, and I found myself on YouTube with one eye on the bandwidth meter trying to make sure that Optus only got to keep the minimum of bandwidth which I've already paid for. They only ended up with a few MB in their pocket in the end.
If it was uncapped, I'd only download stuff when I really had to, as opposed to actively seeking out things to download in order to utilise the last of my bandwidth. Another example of corporate fear and greed causing more harm than good.
