I for one definatly believe that service levels will vary from area to area you live in.
My firm beliefs are that Telkom will decrease its service level (which are already non-exisant) in large metropolitan areas and rural areas.
WHY? With the massive roll-out of wireless technology in metropolitan areas, and wireless not having a monopolous parasite such as Telkom, wireless providers are free to compete, which should, with crossed fingers and great hopes, decrease costs. This will help to relieve Telkom's strangehold on these areas and force them to look elsewhere to maintain their ever sky-rocketing profits.
In the case of rural areas, to roll out a broadband service to them would be far to expensive and the return not large enough to suit Telkom's pocket as there wouldn't be enough users from these areas using the service.
I believe Telkom will focus more on the areas just outlying the urban cities where it is just out of range of wireless technology and cheap enough for Telkom to do a DSL roll-out and go on unchallenged in these areas, thus, the same old story of price dictatorship and fat profits.
This is just theory and speculation, but if Telkom follows its old pattern of going for sky-rocketing profits, rock-bottom costs and an opportunity to have the upper-hand and control, the parasite will jump straight at it!
