I still remember using Palm OS for the first time and having my little mind blown away because there was no save buttons (at least in the version and apps I was using). You edited a document and that's it, it was saved. Like writing on paper.
Nowadays a lot of applications behave like this but back then it was a very different from everything I had ever used.
