Despite not showing the device at CES, Asus reportedly has a new e-book reader up its sleeve, the DR-570. Sources indicate that it will sport a 6-inch OLED color display, and boasts a 122-hour battery life under "real-world conditions," such as streaming Flash video via Wi-Fi or 3G. If that's accurate, the DR-570 could make for a competitive alternative to devices like Amazon's second-generation Kindle.

Some sources suggest the screen will actually be 5.7 inches with a resolution of 768x1024 and a 0.03-second refresh rate. Other rumored specifications includes 4GB of built-in storage, 512MB of RAM, a 1,530mAh battery, an SD/SDHC memory card slot, and it only 200 grams -- less than half a pound.

Naturally, no price is available, but the DR-570 is expected to land sometime before the end of the year.
