Besides vi and Emacs, who else remembers Wordperfect, Wordstar, etc. The good old days when you do everything with a keyboard, and keyboard commands. There's a menu bar that you can call up and out comes the menus. You can also memorise the good ol' keyboard commands, and save loads of time. And of course, you don't waste time rendering the page nicely. That happens when you print out.
Well, those days are gone... and this "new" interface is nostalgically reminding me of those days. IMO, it's a fantastic idea!
