I'm no big fan of iBurst, but you're completely wrong about the new pricing. iBurst is by far the cheapest wireless Internet provider, they've dropped their prices a lot. Bandwidth topups have gone down from R199 per gig for all packages to R49 per gig for the 8GIG package and slightly more for each package beneath that. Sure there is their "subscription charge", but if you're using 8Gigs or less per month then iBurst is still cheaper than ADSL, especially if you're in a good reception area and can get the full 1Mbps.
Like I said, I'm no fan, but I'm starting to get tired of posts about iBurst's new prices being higher now, when the facts clearly say the opposite.
