Does Moore's Law Help or Hinder the PC Industry?
An anonymous reader writes to mention two analysts recently examined Moore's Law and its effect on the computer industry. "One of the things both men did agree on was that Moore's Law is, and has been, an undeniable driving force in the computer industry for close to four decades now. They also agreed that it is plagued by misunderstanding. 'Moore's Law is frequently misquoted, and frequently misrepresented,' noted Gammage. While most people believe it means that you double the speed and the power of processors every 18 to 24 months, that notion is in fact wrong, Gammage said. 'Moore's Law is all about the density...the density of those transistors, and not what we choose to do with it.'"
The core of their argument is that instead of actually delivering same performance at lower prices, Moore's law delivers more performance at same prices. i.e. you can buy Cray-1 level performance for $50, but you can't buy Apple I level performance for $0.001. The second level of their argument is that this march of performance forces users to keep spending money to upgrade to the latest hardware, just to keep up with the software.
