The enTourage Pocket eDGe Dualbook is one of the funkiest Android devices on the market. It opens like a portfolio and on the right you have a 7″ WXGA 800×480 touchscreen, fairly standard fair for an Android device. But on the left you have second screen, but this one is a 6″ 800×600 e-ink display that you can take notes on using a stylus. It has a 1.2GHz CPU, 3GB of on-board storage, a microSD slot for expansion, 802.11b/g WiFi, Bluetooth, and a full-size USB port for a keyboard, memory stick, etc. The only real drawback is that it runs Android 1.6 Donut, which is getting kind of old at this point.
These launched last year for $399.99, and Amazon still sells them for $179.99, but Woot has them for just $79.99 + $5 S&H. And these units are new, not refurbished.
