Plastic Logic E-Reader

Plastic Logic has a new e-book reader coming out early next year that looks pretty interesting and should give the Kindle DX some competition. Here's some preliminary specs on the device:

• The device will be slightly larger than the Kindle DX and have a touchscreen.
  
• The device will be marketed to business users which probably means it will be priced higher than the Kindle DX. The Kindle DX currently sells on Amazon for $489 with free shipping.
  
• The device will have a built in 3G radio for access over AT&T's network and also have a built in WiFi network.
  
• Barnes and Noble will manage the devices electronic book store.
• In addition to e-books, the device will display several other document formats including PDF, DOC, DOCX, XLS, XLSX, PPT, PPTX, JPEG, PNG, TEXT, HTML, BMP, RTF and ePub.
• The first version will be grayscale but Plastic Logic says color is "in the works".

Here's a short video from CNN that includes Plastic Logic CEO Richard Archuleta demoing the new device.

I'm wondering how long it will take before we see heavy bulky textbooks replaced by devices like these.
