As you can see in the following video, Pocketbook is working on two 13.3" ereaders, one which runs Android and has a touchscreen and one which doesn't have a touchscreen. Both devices have a 13.3" Mobius E-ink display and are theoretically aimed at the construction market as blueprint readers.
The Cad Reader is the more expensive model, and it will run Android on a dual-core CPU, This effectively makes it a potential E-ink Android tablet (just as soon as a hacker bypasses the Pocketbook software).
The CAD Reader Flex is the cut-rate model which lack a touchscreen or fancy software. It is literally going to be an ebook reader, and its lack of a touchscreen is going to make it almost completely useless for its intended purpose.
I ran this by a construction engineer, and she said that a 13.3" screen is workable for viewing blueprints, but it will still require a lot of zooming and scrolling. The Cad Reader Flex has no touchscreen and that is going to make it very difficult to scroll or zoom.
But on the plus side, the video hints that you might be able to use the Cad Reader Flex as a secondary display paired to your mobile device. That might prove somewhat useful, and if this device is matched with a capable companion app running on your smartphone then it might not be quite as useless as I expected.
But we'll just have to wait and see. The Cad Reader and Cad Reader Flex will hopefully hit the market some time in 2015.
