Making movies on the iPad is pretty simple. I will share more later, but you will need iMovie. I found the app Clipish Pro to make screens with text.
For school videos, this is an easy alternative. Another essential for me is dropbox which let's me quickly move video from my iPod touch to iPad. (I know icloud will do this eventually, but for now, this is what I use.)
Very interesting way to use iPad. Can't wait to try it!
