You don’t really ‘post in pages’. But you can write a Post, categorize it, then use category type archives with the Category Widget to display access to those posts.
Also, look at using the Static front page feature in Administration > Settings > Reading

What if I want a page at the top called “Product Review” and then I want to be able to post mutliple posts in that page, just like I can post to the default page over and over. I can only type something in the page and not post under it. So does WP not support this? If it doesn’t then I think it would be a very nice feature to add in, and I can’t believe that it doesn’t already.
You are better off having a category called Product Review, then use the native category archiving ability to show those posts.
If you go with categories, you can create a page call Product Review then use this technique if you have a navigation menu of pages:

Or if you have a theme that suuport the new menus you can add a category to the menu.
