I think of Stroustrup's book as a reference manual. It is very comprehensive in covering the standard. Fact is that you don't learn to program by reading books any more than you learn to play a sport by reading books.
That is how I've ended up using his book, but what is the appeal of a heavy, printed reference manual? I could only make sense of the idioms and patterns in C++ by reading the Guru of the Week articles at the same time:

It's written more lively and opinionated. Also, it's apt-gettable on Debian and Ubuntu :).
