Moore's Law

Moore's laws says that
" the number of transistors per square inch on integrated circuits had doubled every year ".
Luckily that trend follows still :-)
Even though i have a 2.8 GHz processor PC with 512 MB, it is very slow.
Nowadays 30% of my processor is used by the Virus scanner most of the time and aprox 10% is being used by the Desktop search engine to index the files, etc. aprox 5% might be used by the spybots... etc..
The left out is only 55% :-(
I think the hardware should grow at the speed of square of Moore's Law, i mean
" the number of transistors per square inch on integrated circuits had quadruple every year ". :-)
