I long ago changed to a newer version of Windows because I bought a new machine. I have a stocked 3.1 system that is doing very well. I also have a car, as a spare, that is a 87. Both the computer and the car are tools. My drill press is 25 years old, and no one has suggested that it can't drill.
Lets keep consumerism and function as separate notions.
I don't deny that new products have features that make them attractive and even more useful. What I don't care for are your reasons for usiong an older machine and operating system. After reviewing what I spend on harware and software upgrades I have come to realize that the increase in productivity is not equal to the costs. The debugging alone takes hours. I am sad to see Windows 3.1 finally go to the grave.
