The hard copy is great but the kindle version is not user friendly. Bought this so I could have it on my phone and easy reference esp if in non theatre locations where I don't carry my bag and books etc. lack of a table of contents makes it cumbersome and time consuming to navigate and find what one wants ....not what one wants in a portable "emergency" reference. Hope they improve this and let us update the version for free when they do. Hard copy is much better.
