have an old Asus net book eeePC. I've loaded with puppyLinux a varient of Ubuntu with very small footprint. It's about 12 years old. Have to rebuild the battery pack as it stopped holding charge about 7 years ago. It's very low on my priority.

have Toshiba laptop after my father died 5?years ago. He had it for about 3 years. Screen is crystal clear sharp but the touch pad and WiFi are dead. Not sure if I want to add external mouse and USB based WiFi. Besides its XP and sure I could reload it with another Linux. but another laptop?

have dell b120 laptop it's about 8? years old. It used to have Mandriva distro of Linux but Mandriva is no longer so switched over to Ubuntu Linux. I need to reload the software. I've upgraded the HDD inside from 40G to 120G. Everything in it is working.

my desktop is 5 years old and runs win 7.

My desktop supercomputer is 4 years old and runs CAELinux. It does not go on the internet!! supercomputer?? It has a thing called disk array, 96G of fastest of DDR3 main memory, boot drive is 120G. thinking of switching over to 240G SSD. It runs a thing called CUDA. I think it has over 1000 numerical processors inside so it runs over billion calculations per second. I need to go and look it up.

WiFi network died after 4 years so took it apart and replaced a bad component and its working. Got very lucky with the bad part. One of few components that can be replaced.

And we've had things that went bad in a year or two and just had to throw it away.

But most thing should last 5 years or more. The other thing to keep in mind is that something mundane as 240G SSD (solid state drives) have over 1000 billion transistors. Just think about it what's the chance of something going bad? 1000 billion parts!! Can you even comprehend such a big number? It boggles my mind.
