I don't actually get the whole 40mb bashing thing.
Vodacom and MTN (who most people seem to like around here) have been offering even lower data packages for ages, and at worse prices. Yet for everything iBurst does you get a page of comments about a 40mb offering. It's not like they force this on anyone or don't offer anything higher, and R50 isn't a terrible price either if you want this for some reason.
Many of the ADSL articles here are about 1GB combined packages, which are almost as useless seeing you're meant to actually use that over a month with an ADSL line, obviously not the purpose of a 40mb offering.
But tricking people who don't know any better into signing up and paying for the terrible bandwidth booster prices is a problem.
