I ask myself this from time to time. It's hard to quantify quality, but I'm certain that the exponential increase of power in todays PC vs. that of a PC from the 90's is not reflected in an exponential improvement of the vast majority of software currently using this power. It seems that the more power that there is available, the sloppier the use of it. I wonder if someone already formulated some kind of law that describes this phenomenon :-)
