the number of engineers and geeks i know that are using hardware that was out of date when they hunted down and bought obsolete hardware is constantly growing.
sometimes it's for a better keyboard (apple), sometimes it's for a better build (ibm thinkpads v lenovo), sometimes it's for a fondness of hardware they had prior to their current hardware.
new hardware just doesn't excite the way new hardware did even 20 years ago. with new oses and crapware like minix baked into every intel chip i just want hardware and software that works for me and me alone.
One reason people who could buy anything are choosing older tech over the newest releases isn't nostalgia or to save money, it's because a lot of new tech products are regressing as useful features get removed to increase profit margins, enable some trendy style or new business model. Hell, it's getting hard to even buy a TV without built in "smart" features and advertising that can't be disabled.
