160MB+ a day. Everyday. That's almost 10x more I am using now.
You use less than 16MB/day average? Wow, how do you manage to use so little? I'm curious, is that actually you making an effort to 'ration yourself', or is that really how little you would use 'naturally' if left to your own devices even if bandwidth was cheap like in other countries? I easily use 160MB/day, and that's before I even actually start getting anything useful done or done anything 'fun'. Consider, for example, I have a typical new desktop computer with Windows 7 ... just off the top of my head, the following are minimum requirements I've had to download recently (over Vodacom 3G, ouch, because Telkom can't be bothered to add ADSL ports in our area):
1. Windows updates: +/- 700MB
2. Anti-virus + updates: 100MB+
3. OpenOffice: 130MB+
4. Latest NVIDIA graphics card drivers: 160MB+
5. Motherboard drivers: 70MB
6. Other miscellaneous drivers: 200MB+
Then I also have an laptop, which also needs drivers, Windows updates, anti-virus updates etc., and a few virtual machines, that also need updates. Daily email throughput is at least typically 20 or 30MB. Then I run some basic Rosetta@home (and SETI on the GPUs), that's another maybe couple of 10's of MB's a day, and that's hardly something extreme. Then I have to VNC in to some work machines regularly. Basic transfer of miscellaneous files to/from work and custmoers, typically 30MB to 50MB a day. Web research and referencing for work purposes, easily another 20MB a day. PostgreSQL, 50MB+. xampp, 50MB, TortoiseSVN, 18MB, NVIDIA system tools, 90MB, VirtualBox, 77MB. JDK+Netbeans, 200MB odd. Then many of these apps need to get updates too ... Java, Chrome, FireFox etc. I have one Mac machine that needs about 1GB updates, I'm not even going to try update it at this stage ... in the rest of the world, this would be seen as ridiculous ... while you weren't watching, the computer industry got bandwidth-hungry. I sadly don't even try update my Linux machines/VMs either.
This is just normal usage .. work stuff, updating, drivers, email ... this is before I've even started doing anything fun (and LEGAL), like trying to watch an episode of Colbert Report (which I sadly just can't afford to now) or a few YouTube videos. You talk like actually just simply using the Internet, like most the rest of the world takes for granted, is unreasonable and dodgy and some kind of 'abuse'.
If you aren't even updating your Windows, you are in for serious trouble, like having your Internet banking hacked. Just a small handful of Windows machines updating each month is enough to easily rack up a GB or two a month.
I can't wait for this Cell C thing to be available in my area; it would help save me from the small fortune I'm forced to give Vodacom each month currently. 5GB would be just-just enough for me to 'just get by'.
