From the Android Central Forums 

Android Central Forums user milomindbender has posted one of the most complete and detailed guides I have ever seen for introduction new Android users to the features and functions of their phone. The guide features everything from a basic overview of the OS to a list of the most popular and useful apps in a number of categories, all with great pictures and diagrams to illustrate the topics being covered.

Any readers that are new to Android or thinking about switching to it should head on over right now, and probably bookmark the thread as well. Even if you are a longtime user of Android, head on past the link to appreciate the quality and effort that went into this guide -- who knows, you might actually learn something new, too!
