Sean Sheedy, a representative from Nextel's Wireless Data Services groups, will discuss the experiences and challenges he encountered while designing the user interface, data entry, and profile/class architecture of some of the MIDlets that will ship on Nextel's Java-enabled wireless handsets.

Specifically, Sean will bring to light implementation issues that are not obvious from the MIDP and CLDC specifications, including presentation, user interaction, program flow, and the use of a handset as a computing platform. In addtion, memory utilization, application management, and the nuances of wireless data communications will also be covered. UI controls will also be discussed, including the reasons behind Nextel's decision to favor custom controls over those provided by the environment, and the costs of doing so. Finally, Mr. Sheedy will debate the need for important features currently not found in the MID profile such as floating point math and telephony.
