Bridgestone has risen to second in U.S. golf-ball sales by exploiting a niche in low-compression balls, but any new short-ball designs will require a bundle of new techniques and processes, the best or most efficient of which could fall under a competitor's patents.

And you only have to look under the hood or crawl beneath the car to see a technological nightmare: A low-compression flathead V-8, cloth wrapped wires, a crude carburetor, leaf springs and no shocks, big mechanical brakes that were about as useful as an anchor, and a differential the size of a melon, to appreciate that this car was a polluting, rattling, death trap.

However, much as it wouldn't want to sell low-fidelity music or movies riddled with compression artifacts, it must do a better job of consistently matching optimized apps to a tablet audience.
