Hehe - just a few months ago I let DH take the peripherals over 5 years old down to the recycling center. Good bye 1400 modem, dot matrix printer, Cat scanner... However, I hang onto my old HP tower with the floppy and 4x cd drive in it, and all the software to boot. We kept Win95 on there and used it for kids' software for a long time. When my mom passed and we couldn't find her will, I became the hero because I could load her old legal software and pull up the documents. Of course the soft copy was not legally binding, but it was a great help to my siblings & I. My pack-rattiness saved the day again, much to my darling husband's chagrin.

So the lesson may also apply to home life.

PS I don't recommend that everyone keep everything forever, just saying that I do.
