Tablet mode meaning you use it for doing artwork on a desk. Like a Cintiq. This is a productivity machine, not an iPad competitor. 14" is too unwieldy for arm handling. No one wants to draw while holding with one arm anyways.
Disagree... a light 14 inch tablet is not too unwieldly (and it is light for its size compared to a normal tablet) to use. A larger screen tablet is actually better and even apple has realized this with the ipad pro.
You want to talk unwieldly... that would be this device flipped around at almost 4 pounds.
