Apple Thoughts: Inkling Provides Text Books for the iPad

"A new developer, Inkling, is bringing a variety of high-profile school textbooks to the iPad. The first four are from McGraw-Hill, and described as best-sellers in biology, economics, marketing and psychology; these should be available today, at an early cost of $3 per chapter or $70 for an entire book."

This is a good start, but I still think that the prices are too high when you are talking about a digital version of a text book. I love the interactivity, and I think that when more sources become available, they will lower the price. You can see what it's all about at the Inkling site, or check it out on iTunes. What are your thoughts?
