There are plenty of e-book readers doing the rounds at CES this year, arriving alongside the news that Amazon's Kindle DX will finally be coming to the UK

One of the most notable efforts was Spring Design's Alex device (pictured left). This Android-powered reader has two screens, a bit like Barnes & Noble's nook, with a 6-inch monochrome e-ink display above a 3.5-inch colour LCD display for internet browsing over 3G or Wi-Fi.

The fold-open Entourage Edge (right), on the other hand, has two 10-inch touch-sensitive screens.
