The second step toward the new computing is inclusiveness, what I call Universal Usability, enabling all citizens to succeed in using information and communication technologies to support their tasks. This goal leads to designs that support users with new or old computers, fast or slow network connections, and small or large screens. It should make possible participation not only by young and old, novice and expert, able and disabled, but also those yearning for literacy, overcoming insecurities, and coping with various limitations. Responding to these digital divide challenges will take hard work, but we have come to learn that diversity promotes quality. Accommodating diversity pushes designers to produce higher quality for all users.
Emphasis mine because, well, damn.
