I have a K4SO. I thought I was buying another K4, for my dear friend.
Instead I received the Kindle 3G with the keyboard.
To buy a K4 is $109 and the K3G with keyboard is $189.
K4 has 2GB and K3G has 4GB and external speakers...
Soooo, I was going to keep my new e-bay purchase K3G keyboard, and give my friend my almost new K4SO refurb.
I am happy. Really and truly.
