As a test, I just downloaded the latest skyview installation manual (596 Pages) to my ipad book application. Total time - less than 30 seconds, and I’m currently on a home wi-fi network in a far away place where the connectivity is not that great.
I could also have downloaded a “red lined” version that shows me the latest changes...
Since VFRG is primarily a reference document How could reverting to an online version be safe unless there is a change log and marked up version as well? One would never know what has been changed. Same goes for paper.
