The iPad 2 was released in South Africa on 29 April 2011, although I doubt there will be sufficient stock for some time, given that even in America, with the order from Apple directly, the waiting list is about 6 weeks. Most people obtain iPads from other resellers who got into the queue early, and sell iPads at a mark-up.
In other words, the popularity is so high that most people are paying more than the retail price to actually get their hands on an iPad and there can be no doubt that whatever stock is coming to South Africa will be very limited, and of course it is going to leave anybody who is selling the original iPad with an out of date product, that they will now struggle to sell at anywhere near the retail price.
