The Pocket Edge is composed of two screens attached by a common hinge. The left screen is a pen-responsive e-ink display measuring 6 inches diagonally. The screen on the right is a 7-inch color LCD running a custom version of Android 1.6.
In addition to the flexible hinge, the Pocket Edge's LCD can be oriented to face in any direction. Coupled with an external keyboard, the Pocket Edge effectively doubles as a word processor or e-mail/Web terminal.
The BlackBerry-style trackball used on the original Entourage Edge has been replaced by an optical trackpad on the Pocket Edge. We can't yet say if it makes for a more effective interface. If nothing else, it means you won't have grunge collecting on a trackball.
Here's what the Pocket Edge looks like during a typical use case. On the left, you have your marked up copy of "Wuthering Heights," and on the right, you have a Wi-Fi-connected Android tablet ready to pull up a Wikipedia reference, manage your bookmarked entries, or view any color images that might be associated with the book.
The color screen of the Pocket Edge runs a custom version of Android 1.6, and includes apps for music, photos, videos, Docs to Go, and more. It does not, however, include Google's Android app store, so the potential for expanding the Pocket Edge's capabilities with apps is limited.
