I'm sure you've seen the "Web Edit" functionality as described in the sneak peak, but did you know you can also do inline edition of list items? It's pretty slick… by default however, inline editing of list items is not enabled. You must alter the view to enable it. Here's how to do it (pretty easy stuff):

STEP 1) Navigate to your list. In the ribbon, click List, then click Modify this View:

STEP 2) Scroll to the bottom, and expand the Inline Editing plus box. Check the Allow inline editing box and click ok:

DONE!

Now test. Notice you now get a "New" icon that wasn't there before. When clicked, you can add a new item into the list without needing a post back:

Also, when you hover over an existing item, you can click the edit icon and start editing the item right inline:

LOVE IT!
