You have your dimensions wrong, with the larger screen it would be ideal for Designers, Architects, Artists.. so it would be 16-9 ratio,
not squared. Also with the narrower bezel it will only be slightly bigger over-all.
Here's a place to checkout screen-sizes: http://www.displaywars.com/9,7-inch-4x3-vs-12-inch-16x9
These images don't show widescreen but the Wacom does 2nd in view.
