It turned out not to work reliably with 286 and faster processors.
It's possible to make a very shrewd calculation that the increased productivity allowed by a faster processor might pay for itself fairly quickly.
Hackles up, immediately: unlike faster processors, humans do not create gravity.
A faster processor is nice, but more memory is mandatory.
Next Iphone however will be a better competitor with front facing camera and faster processor.
Even default apps, such as the camera, benefit enormously from the faster processor.
Demands for faster processors with larger memory to run newer applications software are increasing.
Adding more desktop features, faster processors and so on has also increased the appetite for power.
In other words, no longer is Intel's success assured so long as it efficiently stamps out ever faster processors.
The faster processors on the fancier models are not likely to produce noticeable performance improvements.
