I used to think task bars were pretty neat, back in the 1990s. But once I started keeping more than a dozen windows open, it became a waste of space. And now that I typically have 200+ windows open, the concept of a taskbar is ... like trying to get a fish to ride a bicycle, or like having a rock in my shoe. It gets in my way and provides no benefit to me.

But that's okay. I don't have to use one. Different people have different needs and preferences, and their choice to use a taskbar-free workflow doesn't interfere with their ability to get serious work done.
