Last week, Symbian announced Symbian OS phones rose 131% in Q3 2005 to reach 8.54 millions. Read the complete announcement at Symbian site. Symbian OS is currently the most popular operating systems for smart phones, and now it has been getting more popular in PDA too.

What I am more interested is the market share of smart phones. Unfortunately, I don’t have the number of market share in Q3 2005. The latest number that I have is the report from Canalys for Q2 2005.

Smart Phones Market Share Q2 2005

Symbian OS is still dominating the market by more than 60% market share. Microsoft with their Windows Mobile is the runner up with more than 15%. PalmOS from PalmSource has less than 10% market share. After that, we have other operating systems, like Linux.

What is going to happen next year? My feeling says that we will see a war between Symbian OS and Windows Mobile. Why? PalmSource has been bought by a Japanese mobile content provider, called Access. Meanwhile, Palm is jumping into Windows Mobile by announcing Treo 670. It is likely that Palm is going to release more and more Windows Mobile devices.

It would be interesting to see the war between Symbian OS and Windows Mobile. Symbian OS is from Europe and Windows Mobile is from the US. About 80% of Symbian OS devices are from Nokia, which is also European company. What is more interesting; Symbian OS is more popular outside North America, unlike Windows Mobile.

Who will be the winner? Nobody knows. I have tried to list some strong and weak points for each operating system.

Symbian OS:

  • [+] Symbian OS is the market leader with large installed based devices. It has been growing very fast too.
  • [+] More and more third party applications are developed for Symbian OS. Symbian claims there are already more than 4400 applications for Symbian OS.
  • [+] From the technical point of view, Symbian OS, which is originally from EPOC, was developed from the very beginning as the operating system for mobile devices. It is designed for devices with limited processor power, low memory, always on, limited battery power and most importantly always connected.
  • [-] Symbian dominates the market is mostly because of Nokia. What is going to happen if Nokia switch to another operating system? We have seen Nokia just released Linux device, Nokia 770.
  • [-] The learning curve of Symbian OS is very steep. There are a lot of “strange” concepts in Symbian OS from developer’s point of view, such as active objects and cleanup stack. It might affect the growing number of third party applications.

Windows Mobile:

  • [+] No single company dominates Windows Mobile devices, unlike Symbian OS.
  • [+] The users, who are familiar with Windows 2000/XP, will feel “at home” when using Windows phones. It is one big advantage.
  • [+] We can expect to see third party applications will grow very fast. Windows Mobile has .NET Compact Framework, which make porting applications from PC is very easy.
  • [+] Since it is a Microsoft product, it integrates with other Microsoft products very well, for example Office, Outlook and Exchange.
  • [-] Windows Mobile is originally an operating system for PC. Although most of Windows Mobile codes are written from scratch, some mobile features are one step behind Symbian OS, for example telephony stack used for voice calling. However, Bill Gates recently said the telephony stack should be better in Windows Mobile 5.0. Another example, the first 3G Symbian OS phone was released about 3 years ago in Japan, while the first 3G Windows Mobile phone was released just last month.
