I got my hands on an Alex on January 9, 2009 2010 at the Marvell booth at CES in Las Vegas. I was VERY impressed with the sensititivity of the touch screen at the bottom of the device, and the slim hardware. This looks like what the nook should have been. Here is the video that Darlene took of my experimentation. The Marvell booth had an Alex in a black case and another in white, both stunning.
