How exactly would one hold a 32" tablet, or situate it at a desk? Arms grow very tired operating horizontal touch screens, and if the screen is on a table, angled, it's awkward to sit and look at.
There should be a stand that holds such a tablet at an angle comparable to a drafter's table [1]. That especially combined with a Wacom digitizer would be perfect for a lot of creative professionals.
Ha ha. Ridiculous. The reason why smartphones and some tablets are popular has less to do with touch than with size. It's pleasant to hold a small screen a foot from your face for reading and watching videos.
