There's an OS manufacturer whose products run very fast on high speed
state of the art PCs. Unfortunatelly, I don't have a state of the art
PC, nor do I want to buy a new one every year, so I want to squeeze the
most out from what I've got. Besides, Linux runs faster than the
mentioned OS on a state of the art PC, so I'd prefer to run Linux if I
needed a state of the art PC to get the job done in the first place. I'm
sorry, but this is a new age of rational thinking where every little bit
counts. And it's my rational thinking that wasted resources gradually
add up.
