My advice - read the book. It's amazingly accurate. Then read it again once you have experience; you'll be able to appreciate it a whole lot more.
It's not a management book, per se, but it's great for gaining undersanding into why people work and what truly motivates them.
EDIT: His talk at the TED conference:
Microsoft no longer does this. It shows.
I think its good, but it's been so long since I was at this stage and read it (late '80s) I'm not 100% sure.
That said, I've not regretted one bit reading every apropos book Weinberg had written through the '90s (which is about when I stopped reading these sorts of books).
