I found this video, but I'm not sure of the date. It seems recent,because the announcer speaks of it as a "holiday gift".
First, they talk about "several" versions available. I'm only aware of 3.
Then, the lady they chose to use it is demo-ing the K1!
They make no mention of the thousands of free books available.
They refer to the kindle for pc as a place to put your books "after you've finished with them"
I just don't know who does these pieces.......
