The other day I saw this (link) about Adobe Digital Publishing Suite and was briefly interested in it. I requested a demo to learn more about it, but somehow I was never able to learn much about it and soon I just forgot about it. Later today I noticed I have two updates for Indesign (both CC and 2014) but discovered it was actually to update them with DPS Desktop tools. But, I have not updated them....just not yet!! I don't know if it is because I had shown interested in Digital Publishing Suite that the tools are automatically added to InDesign in my account? And does it cost extra if I have to use DPS Desktop tools? (It never said anything about how much it cost to use Digital Publishing Suite anyhow.)
Honestly I don't really know about Digital Publishing Suite...not enough info...and I'm kinda concerned because I could unwittingly have done something I am not ready for, and could end up paying hidden costs I know nothing about. :S
You’ve nothing to worry about. The tools are updated every 8-10 weeks and if you’re not involved with DPS then you don’t have to have those panels open at all.
Digital Publishing Suite is basically an addon to InDesign application and comes as an update.
Digital Publishing Suite is meant to create digital publication for different mobile devices e.g. iPhone, Android, Kindle etc.
Please refer the following overview article and video tutorial.
Hope this helps.
