Just as a single data-point: I still had an old Crusoe-based TC-1000 [1] convertible lying around, that must be > 15 years old by now. About two years back I gave it a new hard-disk (some PATA to flash adapter), replaced the battery, upgraded to 768 MB RAM and installed a Devuan i386 OS on it (a Debian derivative). Even was able to make the pen work again (that needed some X-server source code hacks). The computer is somewhat sluggish with huge software (like Firefox) and especially software that does JIT-compilation, maybe due to limited size of the "code-morphing" cache. For simple java programs the only way to make them start up timely was to fully disable the JIT-compiler. But other than that it's a usable x86 machine (and all other laptops I know that are of similar age eventually failed to boot much earlier).
