First off I would like to say technology never stands still. Why do you think what you have now is because engineers are always striving for more, better.
It is invetible that there will be faster processors out. Better memory, hardware, etc.
So I am tired of hearing...
'My computer is faster like yours!'
Like small children.
So lets say they never got faster, and you were wishing for a faster PC. And there was none. What would you do? Get a life? ;-) (like I have one, especially since I got my 4.2's)
I am running dual p3's at 1ghz w/512 megs of ram and I am sure there is something faster right around the corner. But I went from a p2 300mhz w/128megs or ram.
So it is a quantum leap for me. If your pc satisfys your needs. Then hell, or if you just want to have bragging rights. Chuck out a couple of grand every year.
