You want to check out some apps, and you are a visual learner. Sit back and watch through videos dedicated to iPad apps for the classroom on the Youtube channel "iPadagogy". There are several short 5-10 minute videos, each video covering the use of an app in education. If the app is extensive, like Evernote, you may find a few videos in order to cover all the features. A great resource for teachers using iPads in an educational setting.
