Query: RealBasic is not definitive.

After wishing for many months for a programming language similar to Visual Basic for the Macintosh , I was immediately pleased when I heard of the RealBasic announcement. I looked for books on the application and then heard of RealBasic-The Definitive Guide. Great! I thought I would finally get down and dirty with RealBasic on the Mac. Unfortunately I was disappointed as I read this book it became apparent that it was more a computer science tome on OOP. It lacks useful practical information on RealBasic and any useful illustrations to back up the facts, as most VB books do. In fact it is mostly a rehash of the manuals RealSoftware gives away free on the web. I found myself consulting the manuals with this book in hand to make any sense out of it. My conclusion, caveat emptor.
