as I see it, you must think of cost, how much of a bargain would it be to have me the potential buyer purchase such a device, and not have two separate ones instead. Another key aspect is the battery life, big screens mean your battery won't last that long, and it would suck to have both your phone and tablet dead.
I think if these 2 are resolved, people will consider buying such a device.
