I prefer to read ebooks on my iPad as ePubs, so I’ve converted the current draft of “The DSC Book”. I’m pretty happy with how it turned out, so am sharing it: http://1drv.ms/1xZUYpP
Problems I know about: the sponsor pages show up as unnamed chapters in the table of contents, and iBooks doesn’t respect monospace font styles.
If you use this eBook and see any other issues, please let me know. I plan to convert the other eBooks in the PowerShell.org library at some point.
