You can also see in this photo that I began making the double cross bollards!

All Contacts in Outlook can be labeled with a photo of the person, which you add by double clicking on the small head icon in someone's contact card and then choosing a photo from your collection.

Perhaps the best example of this is photo viewing: you flip between pictures by simply flicking your finger across the screen, and you double-tap to zoom in and out, just as you would on an iPhone.
