Two weeks ago I started a Mac OS 9 workshop for new young people to enable them using the machines as well (at a public space). I planned 2-3 hours of basic finder usage, and understanding of the system in generall as the spacial metaphor.
After I did about 40 minutes of introducing Mac OS 9.2.2 to a 20 year old new user (who worked with Ubuntu and XP only before) he stated the following:
"Actually it is Insanity, considering with what Operating Systems we have to stuggle with usually. Especially when there already is such an logical and well programmed System, done long before the stuff we have to use these days."
Of course I influenced him a little bit telling him why I love the system, but his statement was a true and deep realisation he had in this moment (we talked about folders that can only be opened once at the same time and that double klicking at opened folders brings the opened folder to the front, as of modifier keys like ALT-Klick that closes all windows and such).
You can imagin that my heart opened, and I felt totally approved - once again!
And finally he had some new views and thoughts for me as well. For example he said that the sorting of folders not as lists or icons but as keys/buttons (don´t know how it´s called in english Mac OS 9, and usually I do never use them, but I showed it to him) was a forestalling of the recent metaphores of mobile devices like smartphones and tablets.
