Okay simple question I hope. My wife is starting her book publishing biz and will be doing Digial (eBooks) and Print publishing of books. She wants to publish books on multiple platforms including Kindle, iBooks, and Nook which includes Android and iOS devices. She will not be creating book covers herself. Which Digital Publishing Suite should she buy, entire CS or just the Digital Publishing Suite Pro or Single edition? Should do a cloud suscription vs the other method you can buy these Abobe products? She's student so she can get students discount as well.
None of them. DPS is for highly interactive publications. She should be learning all about epub, for what you describe.
That said, as a student she can take advantage of highly discounted rates for Creative Cloud. The first year is only $19.99/month.
