Actually, Amazon does not call their Devices K1, K2, or K3. The most recent device is the Kindle. Users tend to refer the the various generations that way so that it is easier to understand what device you might need help with.
If you go to the Kindle Page for Amazon they have the Kindle WiFi, Kindle 3G, and Kindle DX. I wonder what they will call the new Kindle with Ads...
