Interesting content and attractive layout but it just does not work well interactively. The typeface Is far, far too small to be able to read comfortably and it is not possible to increase the font size. Some of the sections where you are supposed to be able to click and expand do not react to taps
The idea behind this is very good. It is interactive so you should be able to drill down. Unfortunately, the control, don't work very well on my Samsung, Android tablet. Occasionaly you can drill down, but most of the time, this doesn't work, which is very frustrating. The content when you can see it are excellent. Clear pictures and good explanation.
