I also have a 4MB line but the problem is that it isn’t always running at 4MB and there are bandwidth caps to contend with. As I understand the MTN Fibre option the bandwidth starts at 2MB and seems to run as high as 1GB and I don’t think there are bandwidth caps in place.

I could be wrong about that but if I am not and price permitting (the big unknown), this will make Telkom’s DSL offering seem like dial up.
