I do like the information available via the books (they are probably worth more stars) but, I am an ancient total novice at tablets/iPads . . . that manages on a computer to use several skills associated with the time I worked in the print, engineering and railway industries. As it is difficult to receive one to one explanation of the peculiarities of iPads -- because of the blinking virus -- it helps me a great deal if illustrations, even highlighted text, etc is present to progress satisfactorily. Nontheless, I think your books will provide the way forward. Thanks for good service. KInd regards, RayH
