"GUIs have become more colorful and more sophisticated, but
there's nothing that a Mac user of 1984 wouldn't recognize. The
standard WIMP (window/icon/menu/pointer) metaphor has become so
entrenched that it seems the natural order of things. We have
trouble imagining any alternative way for interacting with a
computer."
"And yet the GUI as we know it has failed many people. To the
seeing-impaired, to the physically handicapped, to those who have
very different linguistic or cultural backgrounds -- the GUI ranges
from suboptimal to completely unusable."
"To these people, almost the entire computing universe is an
exclusive club they are not allowed to join."
