I disagree with the premise. Radio Shack was doomed because of exponential curves. The price/performance of consumer electronics is on a crazy curve. A $300 camera today is WAY better than a $300 camera from two years ago. The cost of repairing that two year old camera is staggeringly high, especially when compared to the cost of buying a new camera... that is significantly better than the old one. When you have repairable, hackable, semi-permanent electronics, a Radio Shack makes tons of sense. When you have hermetically sealed, atomic, disposable, depreciating electronics, a Radio Shack is doomed.
