Will the convergence of PDAs subnotebook PCs and cell phones produce an information appliance that will make all of those categories obsolete?

The convergence of PDAs, subnotebook PCs, and cell phones is likely to create multifunctional devices that integrate the best features of each category, potentially rendering them obsolete in their traditional forms. These information appliances could streamline user experience by combining communication, computing, and productivity tools into a single device. However, while they may overshadow specific functionalities of the original devices, niche markets and specific use cases may still ensure the continued existence of specialized devices. Ultimately, the success of this convergence will depend on user preferences and technological advancements.
