Your page says Well, that may be true in Stellenbosch, but out here in the Drakensberg GPRS is twice as fast as dialup. Many people in outlying areas should be advised to get GPRS because line quality deteriorates with distance from the exchange and ADSL is not likely to roll out to rural areas for many years.
Your comments re cost are spot on, I am considering changing from ISDN 64kb to GPRS, as the main connection in our office ... ISDN bill is R2500 per month. I worked out that it was R0.58 per minute (I have detailed logs)... and the most you can download in a minute is 480kb (Assuming that the ISDN connection is 100% utilised during every session then it would cost R1.24 per mb)... and since it is not utilised 100% I just know that it is costing a lot more than that per mb. GPRS would save us money, so what if it is 30% slower. On the other hand if I could drive 30% slower and save a whack of money on fuel, but somehow I dont think I can drive 30% slower.
Cheers,
