The more powerful the hardware, the more the Company's will create software so
Obese / Bloated, Buggy and Unoptimized ...that you will never be able to have a
  "Fast"  PC.
 Why?
 Deals with Hardware manufacturers.
 If a PC operated like lightning, and only an actual computer could tell the difference
in speed between a $500 computer, and a $2000 computer...   Many people
wouldnt upgrade for well over 10 years.
 You have to laugh, when people running 
BSMS Office on a decked out PC is still 
DOG slow on a brand new quad core PC with 8gigs of ram,  a HD with higher
bandwidth and rotational speeds...     As it was when they ran it
back in 500 mhz days and 32mb ram.   

    What a sad sad joke.
