Ihae to sound like a smart-arse, but I had more trouble with the style thatn the content! In fact, I don't think I learned a lot that I didn't already know (from much previous reading on the subject). I think I expected a rather more mathematical treatment and then I would have been in trouble!). I know Hawking had to make a lot of revisions to make it graspable by non-mathematicians and non-physicists, and of course he's not used to writing for them, so I don't criticise the book, except to say it's a bit boring for bedtime reading. Try Richard Feynman's works if you want to learn about "sexy" physics--he was a very readable author.
