Obsolescence:
I have a box of floppy disks somewhere in the basement. I saved them because, well you never know, someday you may need that old data. The problem is, being a Mac user, I don't have a way to read them anymore. Apple stopped supplying disc readers years ago. Many Windows laptops don't have floppy drives and someday soon, most desktops won't either. These things kind of sneak up on you, hence the dusty box in the basement.
It's a good thing I now archive data on CD's. Well, maybe not.
