Are there any droid help or `dummies` books
Nope, that's too device specific. There are plenty of Android books but most of them are written for development purposes (i.e. how to program ect.) not for actual "device use." Search through the threads here and on AllDroid, get your hands 'dirty' (just play around with the device) and you should have a firm handle on it before too long.
You are right to be wary. There is much bullcrap. Be wary of me too, because I may be wrong. Make up your own mind after you evaluate all the evidence and the logic. - Mark Rippetoe
