Yet another ebook e-reader announced at CES 2010, this time with a bit of a twist. The enTourage eDGe dualbook, on sale in February for $490, is an ereader, tablet, notepad and portable media player in one dual-screen device. The enTourage eDGe runs Android and features a 9.7-inch e-paper screen on the left, and a 10.1-inch LCD screen on the right. Like the Alex ereader, it's possible to surf the web while reading an ebook on this device, and it has Wi-fi for fast downloading of digital reading content. The enTourage eDGe dualbook is also equipped with a noise-cancelling microphone, a 1.3-megapixel camera, and MP3 player. It supports ebooks in PDF and EPUB format, and there's already tons of ebooks available at their online store.
