Screenshots are a simple but yet effective tool to use on many devices. I find them very helpful if I want to save information on a webpage and know I am going to be away from the internet. It also makes it very easy to retrieve the information from that photo gallery instead of booting up the browsers and navigating back to the page, that is if you can find it again.
On the PlayBook it is a very simple process to take a screenshot. All you need to do is press the volume up and volume down at the same time and you will hear the camera sound. The pictures can then be found under the photos app.
What do you use screenshots for?
