As I’ve done since the original iPad came out, I’ve purchased all my textbooks as ebooks from various providers. This year I’ve split my books between kindle and inkling. Already I can tell you that the kindle book is very flat and, for whatever reason, very slow moving. Since I read other books using kindle, I wonder if it’s because of the textbooks size. The inkling book is awesome. The simple interface and referential links between the content will make the entire experience way more useful. More updates will come as the semester progresses.
