The last thing I threw away, not donated or sold... a USB mighty mouse. The light wouldn't come on when plugged in.
 
I had a 2013 MacBook Air that I got as my first ever computer for Christmas that year. I used it for a few years, but then I got an All-In-One PC from HP back in 2015. I no longer have those two computers as of today; I don't know what happened with the HP AIO PC, but while my mother was cleaning out her house one day, she just so happened to stumble across the MacBook Air (which by this point was maybe about a decade old), and she "accidentally" threw it out.

For some of my other Apple devices (such as my old Series 3 Apple Watch), I have been keeping them, even though I no longer use them.
