This IDC study examines the evolution of feature-rich mobile phones, introduces a market segmentation for mobile phones, and forecasts worldwide mobile phone market shipments through 2008 by mobile phone feature segment. From its roots as a voice-only device, the mobile phone has evolved into a platform for entertainment, personalization, communications, and business tasks. Whereas basic mobile phones with monochrome displays and limited functionality were once solely responsible for worldwide mobile phone market shipment volumes, feature and advanced mobile phones, along with converged mobile devices, are beginning to gain market share. This study also presents essential guidance for wireless operators, mobile phone vendors, and operating system and platform developers looking to capitalize on this rapidly growing market opportunity.

"Along with the sheer annual volume shipment growth expected within the mobile phone market over the next several years, the transition from telephony-centric mobile phones to applications- and data-capable mobile phones will create a massive opportunity for vendors developing mobile and wireless hardware and software technologies." ?
