"Ordinary" is a Context-Dependent Term

From one of the pages in which Cornell walks you through the process of electronically submitting a dissertation:

For most, a final dissertation or thesis is a large computer file -- too large for an ordinary 3.5-inch floppy diskette.

Dude, where's your web page update?

Of course, what "ordinary" means hasn't changed in a decade; it's simply that what is ordinary has changed in that time -- to the point where I found the statement incredibly funny.

This has been a commentary on the original intent theory of constitutional interpretation ("cruel and unusual punishment", for instance).
