I got the email in my inbox about 20 seconds ago. I also just checked the website, and the order page isn't up yet. From the press release:
Spring Design today announced that the dual screen multimedia Alex™ eReader will be available online at www.springdesign.com today for $399. Customers may visit the online store to pre-order their Android-based Alex eReader supporting eBooks in EPUB, PDF, HTML and TXT formats. With Alex's full Internet browsing using WiFi connectivity, users can read and download books, access online audio and video content including YouTube videos, communicate using Gmail and chat and use a number Google Android applications. Due to localization of international versions with partners, pre-orders placed on the Web in the U.S., will be shipped no later than mid-April.
