I'm sick of getting newer, nicer hardware only to have the new Windows version take up so much more of the system resources that it only runs marginally better than my previous system :/
To be fair, a lot of that has to do with the fact that modern machines are faster than most things they are used for. When the machine already runs your software at full speed, there isn't much else to get out of it. For example, I have a first gen Atom with Ion video that I use for XBMC. In another room I have an i5 for the same purpose. They both run XBMC at full speed, so even though the i5 is WAY faster, I only get a small improvement in usability.
This is also why so many people are jazzed about the ARM processors. If they are fast enough, power draw become the important factor instead of speed.
