5GB bundle for tethering

StarHub in Singapore does have a fair use policy of 2.2GB per day, see http://www.starhub.com/support/broadband/termsa...

This article also implies that Vodaphone has a fair use policy on mobile broadband:

True that what's being called 'Unlimited' data is not literally 'Unlimited' data but, as mentioned above, 10GB is, for all intents and purposes, effectively 'Unlimited' as far as 99% of users will ever care (or be able) to find out.

True, literally unlimited data doesn't really exist, even on a server farm, since at some point you run into hardware or bandwidth constraints that will prevent you form downloading the entire internet again and again an infinite number of times.

For heavy data users, you might run into issues with the cap when, say, trying to download 20 seasons' worth of the Simpsons in 1080p HD video but realistically, I hope there's not that many people out there stupid enough to try such a thing (hint: DSLADSL for the uber heavy lifting will save you many months of waiting).

Also, since the iPhone doesn't do multitasking it'd be pretty tough to use up all your bandwidth if you actually have any friends (whose SMSes, MMSses, Tweets and FB status updates will tear you away from your downloading session each and every time).

On a more serious note, would you be happier if I called it a 100 GB bundle knowing that there's no way you're going to be able to consume that much data (yes, even over a 3G network, keeping in mind congestion, contention, etc)? 100GB sounds less than Unlimited, yet there's no way to hit either

every network has a finite capacity and throughput, not unlike a buffet or brunch. If people start packing the free-flow of drinks and food into containers and bringing it home for a week's supply of food and drink, then other patrons who are there to enjoy the brunch will find that most of the good stuff is gone.

Since most people are pretty reasonable and fair, that means that a minority of people who abuse the system will end up compromising a good deal for the majority of people who plan to use the service in a fair manner, hence a Fair Use policy.

Even a fixed line network served by fiber to a residential community falls victim to such abuse. Have you ever noticed how some areas have particularly slow internet connections? This is usually the result of a high concentration of people who are aggressively using file sharing and bittorrent services, and everyone else who is trying to surf the web for news, watch a bit of YouTube, downloading emails, internet banking, etc suffer as a result.

Is this fair to the majority? Mobile networks have even less throughput compared to fixed line networks. Each cell has a capacity and if 10% of people abuse the system, it creates network congestion, resulting in a very poor experience for everyone else who use the internet normally.

So tell me, how is this fair to people? I'm a heavy user of mobile data, using it for Youtube while waiting, push email from Gmail and my office email system, internet banking, reading news on the go through Google Reader, geotagging locations on Google Maps, and chatting with friends and family on GoogleTalk, and yet even I struggle to exceed 1 GB per month, much less 10 GB.

So please, be fair.
