I want to get a really good book on windows 7
I have been using win7 for a long time and feel very comfortable with it, but I want to try and be a "guru" on win7 and really know all the details
I have a book but it is mostly focused on passing one of the Microsoft tests. So I don't feel like it's really getting into the nuts and bolts of win7
Also, it would be ideal if I could buy it as a pdf file so I could keep it on a flash drive to carry around with me.
