The Bookeen Orizon has a multitouch Sipix display and will be release in May for $250
Bookeen say that the upcoming Orizon e-reader will be available in May (in both the US and the UK). They also update us that the reader will have a multi-touch Sipix display (6", 800x600).
Beside the Sipix e-paper display, the Orizon has 1GB of internal memory, micro-SD slot, Wi-Fi, Bluetooth, accelerometer and mini-USB. It weights only 150 grams, and supports several file formats, inlcluding ePub and PDFs.
Update: We just got word from Bookeen that the Orizon will be available in May 2010, and not April
