One great problem it solves is namespacing all of your styles. I don't have to worry about classname collisions because the bundle handles it all for me. Instead of having one massive global stylesheet, I have a bunch of small, modular stylesheets that fit entirely on my display without scrolling, and I can reason about the output much easier than before.
