>The reality is that even with fairly heavy use, most of them will far outlive the computers they're in.
I'm not sure what the lifetime of a computer is. In my family, we are still occasionally running machines from circa 1995. They work fine. When should I stop using my MacBook? The only reason I'd stop is if it died in a way that can't be cheaply fixed.
I'm curious what useful work such a computer can perform, given that a typical 1995 computer had a 33 MHz processor, 8 megs of RAM and 1 gigabyte of hard disk space.
1995 is a stretch for anything modern but I have kids playing Minecraft on Pentium 4’s (with decent graphic cards though - that is the critical part). These boxes would have been new around 2003 or so.
