Certificates Question

I think I'm missing something when it comes to ADCS. I understand how to create CAs, issue certificates, autoenrollment, templates, and most of the other things I've read about certificate services.
However, I don't understand why I'm doing all this. Example: I issued a certificate to my user account in AD. Now what? With most of the other services, I understand the purpose behind the infrastructure I'm setting up. But with CS, I'm left wondering what I can do with this now that I've setup the infrastructure for it.
Does anyone have some resources to explain exactly what you do AFTER you get your CA setup and your certificates issues?

More systems have been wiped out by admins than any cracker could do in a lifetime.
