An anonymous employer from Samsung has said a 7.85″ device might be in the plans of Apple.
The 7″ segment makes up for a great number of very portable devices, and a segment Apple hasn’t touched yet. I believe it was on Job’s plans, so it’s going to be really the first new form-factor since his death.
Go under 0.4″ thick, and real high res (1280×720, possibly more since they fit 3 million pixels in a 10″ screen!), and it’s going to be a killer device (especially if they take special care of the e-reader functions).
