Learning Unity For Beginners.

Hi everybody, I'm new to unity and have the 4.0 version as of now. I started reading the manual to learn unity as a first timer but got stuck up at some places as they discussed topics that were taught later in the manual. I also watched the videos on the website but found it hard to follow. I'm familiar with c++ and can model worth something in blender. But I have confusions as to where should I learn unity from? Is a book better or a video or any other resource? I'm a beginner to game development on the whole but I do have programming experience. So, please tell me about the best way I can learn unity keeping in kind what I already know. Thanks a lot in advance to everyone.
