Another oldie but goody that many that many people don't realize you can do in the iPhone OS: screenshot anything you're looking at. And keep in mind, when this happens on the iPad, it's at 768x1024 resolution-making it potentially a lot more useful in the full-sized monitor realm than iPhone screenshots.
Push the top (power) and home buttons at once for half a second.
The photo will be stored in your photo library.
