As technology becomes smaller and more portable, it is essential to focus on the purpose of this technology. The way we interact with these devices and the effectiveness of the device as a life-enriching tool depends largely on the design of applications that benefit the public. Although the typeface for a device-based application might not change the world, it is a necessity for changing the individual user's experience. Good experiences are powerful.
Typography should not be underestimated, especially when the margin for error is so small. The means for delivering information in a small, legible, effective manner is here. It is up to the developers, like you, to create the kinds of tools that benefit everyone. Attractive typography is only as effective as the quality of the content. We should not focus on the technology, but rather on how the technology can be utilized. Consideration and compassion should be the means to the end. Clear type is considerate. Caring about what you create is compassionate. Everything else will fall into place.
