I have discovered many things that I wasn’t familiar with when I read about the iPad. I learned about the different ways you are able to multitask on the iPad. I learned how to make a split screen. I can also add highlights and notes to books. To take a screen shot, you press and release the Sleep/Wake and Home buttons. You can annotate photo and PDF attachments in email messages using the powerful markup tools of Mail. You can also zoom in or out of the screen by double-tapping the screen with three fingers. There are many apps you can access from the app store. I am able to use Word Clock to correlate geography with time zones in different cities.
