I maintain my machines to avoid them to fail, I bet my collection of home computers/consoles will work in 10-20 years.
You just have to give them some love 
Yes machines need love :-) but even if i am very good with them there are a few of them that gives me trouble, but it is mainly computer and consoles with cd roms, that gives problems. but i have a sega master system that is 25 years old that still work flawless :-)
