Even though I had quite some difficulties with this book (Hello, dyscalculia!), I did learn a few things by reading this book. I enjoyed the chapter about time travel and finally know for real what micro waves are.
But all in all Hawking writes for another audience than I am. I'm just an interested layman with little knowledge. People who just started getting into physics I'd recommend Neil DeGrasse Tyson. Hawking later on.
