When you publish your page, you will be asked whether you would like to display pages on your blog, with options to show it in sidebar or in tabs or without gadget i.e. by manual linking.
But there are a few limitations with this feature:
1. You can only create a maximum of 10 pages.
2. Separate templating for pages would be a little too difficult(but not impossible :) )
3. The Static Pages are not included in the Post Exports till now.(at the time when this post is made)
