First I'd like to clear up what the 1.13 update was for, and why it was only released on the PE. I reported a bug with the PE where I was unable to use the Optical Mouse after updating to 1.12, as did a few others in the forum as well. When I bought the device, I enjoyed being able to use it without having to interact with the touch screen all the time. This was also one reason why I loved the original Palm devices(pre-WebOS), they worked wonders with one hand. Using the optical mouse, one can easily navigate the home screen, launch an application, navigate in the application to locate the data they need. All of this without even needing to touch the screen. Frankly, I miss handheld devices which had his feature. Unfortunately other tablets, new phones ship with the requirement to use the touch screen no matter what(Apple is to blame for this trend). One handedness is great as us humans only have two hands at any given time. If one hand is taken up, and the other has my mobile device in it, I would like to be-able to hold both of my objects and still be-able to operate both of them. Also the reason why I favor a hardware keyboard over a virtual one(this story for another day).

Now that you know why 1.13 was released... Here's a link to CES 2011 displaying the eDGe: http://www.youtube.com/watch?v=zON6_rZZmLg

It looks almost identical to what we are currently using. Since 2.2 looks very similar to 1.6 on the home screen, you can only assume that the device in this video is running 2.2.
