I think my laptop, a Samsung Notepad with touchscreen. Before I got it it was already used and has been with me for more than 10 years. A couple of years ago I gave it a new life by installing Linux and I hope it will last me another 10 years.
Nice! I have an old PC that was built back in 2012. It has "retired" as a youtube and media machine and has been on every day in the morning for the past 13-ish years. Its running PoPOS mostly because we put a 1070 in it in 2019 to play some games before we got our steam deck.
