I thought it was hilarious. :) I probably still have a hardened roll or two of the fancy silver write protect stickers around here. :)
The silver ones were the good ones. When they started cheaping out and producing plastic ones, the plastic was stiff enough that over time, it caused the adhesive to release, and the tab would fall off.
It produced the same sort of uneasy feeling as a condom with a pinhole in it.
