In your own discovery of your device if you haven't found features that amaze you or set the device apart in your opinion, then there's probably nothing to show off. It doesn't look good when you have to ask others what the stand out feature is.
There are lots of stand out features I love about my S3. My thread is asking what people think are the most impressive for non-geeks.
Generally I have found that handing them the phone with flipboard open, and asking them to flip generates plenty of jaw dropping complements.
