One of the reason for me to use bower is to have the dependencies only relying on your server and not an external CDN. Depending on what you do, that is something you'll want.

Another advantage to this approach is you'll be able to also play with the files, e.g group them, minify with the tools you want, debug with the full source available or only use parts of the libraries.

Also for offline development it's a bliss (on a laptop on the go for instance).

You can do all of this by checkout each project individually and manage them yourself, but it's so much easier to just use hower.
