A GUI observation: Successful GUIs, for the most part, never adapted to widescreens.
In fact, just as widescreen adoption was taking off in the mid 2000s, GUIs instead got *taller*, with things like the Ribbon concept.
@bhtooefr @halfur @coryw I probably should have said "business laptop." All of these closely resemble the Surface family, which makes me think the presence of 3:2 displays is nothing more than a few vendors noticing the economies of scale created by Microsoft and putting its suppliers' panels in their own variants. All touchscreen convertibles or UltraBooks (if that is still what people call them). It would be nice if that sparked interest in them elsewhere, but I'm not counting on it.
