Symbian Savors 2005 Success While Windows & Linux . Predicted to Achieve Mobile Market Parity by 2010

TDG: At 3GSM in Barcelona, Symbian announced that shipments of its mobile operating system almost tripled from 14.4 million units in 2004 to 33.9 million units in 2005, the fourth consecutive year that Symbian enjoyed a growth rate in excess of 100%. At the same time, Symbian's market share of advanced mobile operating systems will decline from 51.4% in 2005 to approximately 22.1% by 2010, placing it third behind both Windows (28.7%) and Linux (26.6%).

Demand for more robust mobile devices is accelerating at a phenomenal rate. With next-generation networks being operationalized throughout the world, mobile carriers are pushing a variety of sophisticated applications which place greater demands on device operating systems. As this happens, more advanced operating systems such as those offered by Microsoft and Linux will become more attractive to handset vendors and mobile carriers.

Allen notes that mobile Linux has already experienced a sizeable boost in shipments during the second half of 2005, something which few forecasters were expecting but a trend will continue as the Palm OS evolves to a software layer running on top of Linux. Microsoft is expected to enjoy robust growth in the advanced mobile OS space by leveraging tight integration of Windows Mobile 5.0 with Microsoft Office and Exchange 2003 SP2.

Advanced mobile devices are distinguished by the use of operating systems with functionality similar to those found in notebook and desktop PCs. They provide true multitasking environments, thus allowing simultaneous operation of multiple applications and inter-application communication. According to this definition, approximately two-thirds of Symbian's 2005 mobile OS shipments could be accurately characterized as advanced.
