Spring Design this morning announced that its dual screen Alex eReader will be available online today (the rumors were true!) for $399. Customers can thus start pre-ordering the Android-based multimedia e-reader, which supports eBooks in EPUB, PDF, HTML and TXT formats.

Spring Design says due to localization of international versions with partners, pre-orderded units placed on the Web in the U.S., will be shipped no later than mid-April.

The Alex eReader features a 6″ EPD screen and a full color 3.5″ Android-based touchscreen LCD. The device supports full Web browsing over WiFi, allowing users to surf the Web, watch videos and communicate with online contacts while simultaneously reading and downloading books. Users can also use a number Google Android applications.

Alex connects to Google’s bookstore with over one million titles, and other book stores that support Adobe DRM.

The Alex eReader weighs 11 ounces and measures 4.7″ by 8.9″ and less than a half inch deep. Users may add their own content or download content to the microSD card offering expansion of user libraries up to 32GB. The Alex may be updated over WiFi and USB 2.0 and comes with headphones, AC/USB power connector and a padded cover.
