One of my all time favorite quotes is by “"Those who cannot remember the past are condemned to repeat it." George Santayana said this in The Life of Reason or The Phases of Human Progress: Reason in Common Sense 284 (2nd ed., Charles Scribner’s Sons, New York, New York 1924 (originally published 1905 Charles Scribner’s Sons)(appears in chapter XII, "Flux and Constancy in Human Nature") if wikianswers.com is to be believed :)
Winston Churchill is credited with a derivative of it that says “Those that fail to learn from history, are doomed to repeat it.” Either way, Adobe seems to not be able to remember the past or learn from it.
At one time Acrobat was the secure alternative to Word. Today it is not the case at all.
