My biggest pet peeve as a user is not seeing what's going on with a loading screen. There's nothing worse than a loading bar that's just an animated looping gif.  Debian based apt-get installs have some of the best progress bars ever, you can expand it to show minute details of what step it is currently on, while also seeing an overall percentage estimate.,(reply>), I run Debian and I really couldn't relate to this video. If there's a progress bar on the screen you can expect it's accurate. Everything just works the way it should.
