Lol. . .maybe we should all think about this in terms of high school chemistry:
speed of light = frequency * wavelength
Thus if we have a processor that runs at 2.5ghz, it's wavelength must be shorter than that of a processor running at 800mhz. And really, what's so great about having a short wavelength anyway?
Maybe if you have a small computer like a laptop you need short waves, but I prefer longer waves myself. Just ask any surfer.
