Speculation: some of the tests fail because a tester is using gestures
that have worked on a conventional touchscreen. The XO-4 has a tilted
XY infrared touchscreen, and so certain gestures become ambiguous when
the fingers cross on XY coordinates.
If so, and the functions can be discovered, then a naive learner will
rapidly figure out gestures which work reliably. The learned gestures
will also work on a conventional touchscreen.
