The keyboard version is A8 single core -- that's why it was canned coz of low processor, moreover it was being produced when it got canned as it was to be released before the kbless version.
and the candybar/kbless version became the consumer device as it was still on the drawing board or the labs so they updated its hardware to make it high powered super specced device for mass market.

now the 92k (as per russian worm) produced are stockpiled which will be given to devs, and the other updated one is which we gona buy.
take it or leave it, thats the story and we the puppets.
