Fitt's law for mobile devices

I've been working on articulating some of the theory behind mobile UI
design, by examining current algorithms and heuristics from the entire

analysis with specific design recommendations at [2], but that is a

edges of the screen, as they are really infinitely large in one
direction. Corners are larger still. Thus frequently used items should

That is the primary question, which relates to a set (series) of goals
(e.g. Make a new document, Open an existing document, Remove an
existing document (application)).

Many more applications is very, very common.
