PR is divided by the number of outbound links on a specific page. And in general most home pages have higher PR than secondary pages since inbound often go to the home page. If you plan this out well many of your secondary pages can exceed the homepage PR value.
In addition to vitaplease comments, receiving a link from a page that currently has no links is better than a page with 2 - 100 or more links. Even better is to get a link from a page which is highly on topic with the page on your site it is linking to. That is, that the topic or theme or specific subjects on your page are also on the page that is linking to you (including a descriptive anchortext).
