Yeah, that's a George Carlin quote, and I'm well aware of it. It's no excuse for dumbing down interfaces like a launcher, or filling it with superfluous features (that coincidentally feed into a corporate clickhole).
Rather than the grim idea that everybody gets an interface the lowest common denominator will grasp, I maintain that everybody deserves a functional, no-bullshit launcher like KISS. It absolutely isn't what you make it out to be.
