Jef Raskin's The Humane Interface

Tasks become habits. No modes, only chording. Only one way to do things. No warning screens, everything is undoable.

Reliable. Everything saves automatically. Content resistant to crashes.

Efficient and simple. Tasks don't take time to perform. Tasks don't take time to learn.

No icons. Purely text.

Zooming UI. No filenames.

No applications. Only commands.

Well tested.

Visually attractive.

How about using RAM only as a cache for persistent storage?
You wouldn't need stuff like config files, separate database files, save files, everything would automatically and transparently be persistend. Hell, you could keep every emacs buffer open forever because it wouldn't make a difference if you closed them or not.

I'm sure it would be slower, and you'd need battery backed storage for it to work properly, but damn it's a cool idea.
