TG Daily is reporting today that according to a designer they met at CES, it would be nearly impossible to obtain a 10" LCD or Oled screen these days.
Apparently, the cause of the shortage would be Apple pre-ordering every bit of 10" screen available on the market.
On the same page, MacObserver just published a shot (featured above) of what they claim to be a "10" Apple Tablet Glass".
While there is no way of knowing how real this is, it supports the idea of the iSlate being a "big iPhone".
But I guess we'll find out soon enough...
