The Swiss use a variety of sleds, from crude wooden frames that go sideways as fast as they go forward, to low-slung sports models that look like a luge and can be steered by warping the runners.
However, displays that only use IPS still appear washed out at various angles, such as when laid sideways in bed, flat on a table, or propped up in a case.
The homescreen itself only functions in landscape mode, and doesn't re-orient when you flip the phone sideways (though we don't know why you'd ever use it that way).
