Now here’s another twist on the textbook Inkling. It appears they are incorporating the Adobe Digital Publishing functionality with a few of their own details.
One thing I really like is the Social Learning feature which allows users to interact with classmates. So, you could ask each other questions and discuss ideas and questions.
You can download the Inkling app, for your iPad, then buy chapters or full books. There are a few chapters, that are free, so I suggest you give them a try. Happy reading and learning.
