Now, that's all fair enough, but what can you do with it?

If you're using a server-side script to generate pages, then quite a bit. You can take information from a posted form, or in the query string, and add it to the session data. You can then retrieve this information and redisplay it , or save it in the database. You can remove information from the session data, and modify it. And you can do this freely within your scripts.
