Unless the Rand really collapses and heads to 20 to a dollar I wouldn't worry. Electronics prices will be dropping despite the low value of the Rand because global demand is decreasing anyway while newer parts are coming out every 6 months or so. The only difference will be that you may not see as significant a price drop. I don't think it'll get as bad as arf9999 says, I don't think it got this bad in 2001 when the Rand hit 13 to the Dollar. Although if the global economy really tanks and demand drops off entirely, manufacturers will
be closing down assembly lines and we may see an artificial increase in
prices, still its no reason to buy an expensive item when the economy is tanking, you'll need that money for food and petrol instead.
