The built-in keyboard offers faster, more familiar data entry and navigation. Applications on Treos with keyboards have been optimized for thumb keyboard navigation, such as writing Treo Mail and instant messages or looking up any name in the PhoneBook using one hand and as little as 3-4 keystrokes or less. With the QWERTY keyboard, Treo can be used with one hand, which we feel is an important feature of mobile communicators. With Graffiti, you must use a stylus to use applications in most cases. Also, Graffiti is a barrier to entry for many people who find it intimidating to learn.
