We don't need a book. We need a vim installer that can do all those things which you will have to otherwise spend time and work endless hours customizing vim to do. The reason why people move to modern GUI based editors is those editors do many things out of the box which you have to otherwise spend time learning and then do it.
I've been using the same vimrc (and gvimrc) for at least 4 years (minor tweaks when something breaks, of course). But 99% of the time, it's identical and set up exactly how I like it, versus the magical GUI IDEs that change where options are, or what they are called. I don't have time for that (and I use the same vimrc on windows, Mac and Linux). Sure the initial set up is difficult. But once it's done, it's done.
And I think that right there is the reason such a tool will never truly catch on. (Nearly) everyone who currently uses Vim wouldn't use it. It is why things like Cream never caught on I think; there really is not as much demand as some people think.
