It's no surprise that more displays is always better, but when it comes to mimicking the act of reading a book, dual displays is a clear step forward. Researchers at Maryland and Berkeley Universities developed a prototype dual-face, modular e-book reader that allows readers to fan pages to advance in a book or via trackball. If you're doing some serious research, the displays separate from one another, allowing one to display in landscape mode while the other runs in portrait. To complete the book meme, the device can be folded over to run in a more compact manner, and a simple flip changes the page. Possibilities for future e-book readers are endless here, so we applaud Maryland and Berkeley for using those research dollars.
