When I see discussions of larger tablets like the Samsung Galaxy Tab Pro and the rumored iPad Pro (both being above 12 inches) reviews always make comments like "gigantic" and other such terms. But in reality these tablets get used at roughly the same distances as a laptop and laptops come in sizes ranging from 11 inches to 17 inches with 14-15 being the norm. So if the weight/bulk of the tablets can be kept reasonable I don't see why we should continue with smallish screens like the 9.7-inch iPad.
