The title is in my opinion slightly misleading. This is a book for IT managers that wants to know what Linux and F/OSS is about. It is also a snapshot in time.

If we look at it as an introduction to Linux/FOSS, it is well worth reading. But if we look to the title and try to look at it from a non-IT managers perspective, it is pure trash.

I'll give it an OK rating anyway, but this assumes you (the reader) is already working in IT.
