I came across this video showing some interesting interface elements for navigating through ebooks:
I have been a big fan of ebooks from back in the Rocket eBook days (Anybody remember this device?), and am really excited that the publishing industry seems to have finally reached the tipping point with going to digital. It’s clear that refinements like these will simply accelerate the ebook adoption process, and I love seeing innovation like this taking place in this space.
My current e-reader of choice is the iPad Kindle app. Amazon’s development and continued support of the Kindle has been the critical factor in getting the ebook marketplace to this point. Of course, Apple’s announcement of iBooks Author last week is a sign that things are starting to heat up here and I’m excited about that as well. Clearly, the future is still up for grabs, and there is no shortage of opportunity for creative minds to evolve and shape this space moving forward.
Kudos to the folks at KAIST Institute of Information Technology Convergence that developed this – it is really well done.


On the other hand, B&N’s Nook has almost all of Kindle’s capabilities, a few unique ones of its own, and dangles the possibility of some interesting software enhancements in the future. The Nook is a dual screen device. It has a large e-ink display on top for reading, and a small touch enabled color display below it for navigation. While it is hard to make usability judgments without living with something for a while, its design seems better thought out and more appealing than the joystick/menu navigation model used by the Kindle. The Nook also has ePub and eReader format support, making it open to connection with other ebook stores as well as public domain titles from Google (as the Sony can as well). The Nook also brings a new concept to the ebook space – lending books to friends. When it comes to the basics, Nook seems to be a good mix of both feature refinement and clever innovation.

Equally important, the Kindle DX includes a native PDF renderer. This means that I could use it to store the incredible number of documents – mostly technical manuals, journals, and brochures – that I end up carrying around with me for work. While being pitched more in academic circles as a device for textbooks, I think it shines as a reader that can address the needs of any technical professional.
