[Uh-Nu-Buh]

Kate is really nice. However, Emacs takes more ram, is slower, provides more features like the Psychoanalysis module (yes, it is JUST as good as going to a real psychiatrist), an Adventure game builtin, and more more more.

Sure, if all you want is a fast, feature-filled text editor with a great plugin architecture and DCOP supoort, then Kate is swell. But if, like me, you NEED something that has a dozen calculators builtin (financial, reverse polish, mortgage, scientific, etc.) an IM chat client, a PIM, a vocabulary builder, a calendar, chess, go, nethack, minesweeper, elite, sudoku, poker, email, news, life, pong, snake, tetris.... Then you need Emacs. Even now they are working on incorporating Dom III into Emacs--with all kinds of extras--tutorial, mismatched mod statements, unit worth calculator, map editor....

Emacs is the IT of IT.
