• Symabian : Nokia 與 Ericsson 一同研發，小軟體也很多但也會比較容易當機。以全球最

大手機市場中國大陸而言，長期以來，智慧型手機操作系統平台市場爭奪戰，根據易觀國際最新公佈的數據顯示，以 Symbian 擁有絕對優勢 。

• Palm OS : 是一種「半開放」的架構，程式設計師可直接取得應用軟體的設

計工具來撰寫自己需要的程式，以共享軟體 (Shareware) 、或是免費軟體 (Freeware) 的方式在網路上提供使用者下載。以龐大的軟體資源來吸引使用者的青睞， 廠商考慮消費者最重視的簡易使用性及效率化，所以 Palm OS 在設計時即以系統的即時性及穩定度為設計的重心，因此就使用者的經驗來說，很少有當機的情況發生

智慧型手機的關鍵：作業系統

• Linux : 是一個完全開放崁入式 OS 系統、軟件授權費用低、應用開發人才資源

豐富等優點，便於開發個人和行業應用。 Linus 互聯網遍佈全球，加上 IBM、 SUN 等巨頭的支持，在操作系統市場異軍突起。他主要都是出現在Motorola 裏比較多，最大的特色就比較穩定比較不會當機，但小軟體比較少。

• Windows Mobile : 是 Microsoft 專門為 PocketPC 或是 Smartphone 所打造的一套開發環境

與授權方式，一般公司如果想要加入生產 PocketPC 或是 Smartphone 的行列，就必須與 Microsoft 特別簽訂相關授權，至於產品的外觀與內含的軟體核心，都是由 Microsoft 建議，量產之前也必須通過 Microsoft 的認證，方能掛上Microsoft 標籤出售。

iPhone OS (Apple)• Pros:

– Strong user growth and data-hungry user base• More than 10 million iPhones sold• 3.8% of worldwide smartphone web/data traffic and 7.8% in US (1)

– Application store creating a vibrant app ecosystem with great momentum• More than 3K applications (~20% free)• More than 1 million downloads

– Powerful technology enablers (e.g., multi-touch, GPS, accelerometer)• Issues:

– App approval process is largely a black-box to developers– Apps viewed as competitive to Apple are often shut down– Downloads highly dependent on “featured” or “top download” promotion in

store– App store is the only authorized distribution channel– Apple / hardware dependent

• Recent news / developments:– NDA requirement: Apple finally removed the onerous NDA requirement– Flash: signs pointing towards development of iPhone flash player

• Development resources:– http://developer.apple.com/iphone/index.action– http://iphoneincubator.com/blog/

BlackBerry OS (RIM)• Pros:

– Large reach and data-hungry user base• Leads US market with 31% of smartphone traffic (1)

• #2 in worldwide market with 11% of smartphone traffic (1)

– Developers not limited to single distribution channel• Issues:

– Developer momentum appears to be shifting to iPhone– Less reach outside of North America– Application distribution more difficult today vs. iPhone’s app store – Users more email focused vs. web consuming iPhone users– RIM / hardware dependent

• Recent news / developments:– BlackBerry Application Center scheduled to debut w/ BlackBerry Storm OS v4.7– Speculation that Storm (i.e., touchscreen iPhone competitor) will be available in

Windows Mobile• Pros

– Strong user reach• #2 in US market with 30% of smartphone traffic (1)

• #2 in worldwide market with 13% of smartphone traffic (1)

– Manufacturer agnostic– >18K apps

• Issues– Current version in market (Windows Mobile 6) lacks support for some popular

technology enablers (e.g., multi-touch, GPS, accelerometer)– Next-gen version will be late to market– Less developer enthusiasm vs. that for iPhone and Android– Application distribution more difficult today vs. iPhone’s app store

• Recent news / developments:– Microsoft to launch “Skymarket” applications marketplace for Windows Mobile 7

(planned for launch in 2H ’09)– Speculation that Windows Mobile 7 will support revamped UI and multi-touch

Android (Google)

• Pros:– Open source => could help accelerate pace of innovation– Manufacturer-independent => could help accelerate consumer adoption– Technology support (e.g., touchscreen, GPS, accelerometer, video and still

cameras)

• Issues:– Late to market relative to iPhone– At least initially, demand is expected to trail iPhone demand

• Recent news / developments:– 1st Android phone (T-Mobile G1) to go on sale on Oct. 22– Sept. ’08: Officially released v1.0 of SDK in Sept– Aug ’08: Awarded $3.75MM to 20 developers in the Android Developer

Challenge

Symbian (Nokia)

• Pros– Massive global reach

• Leads WW market with 62% of smartphone traffic (1)

• 57% market share of smartphones sold in Q2 ‘08– Like Android, being open source could help accelerate pace of innovation

• Issues– Limited reach in the US– Application distribution more difficult today vs. iPhone’s app store

• Recent news / developments:– June ’08: Nokia announced plans to acquire full ownership of Symbian and

start the Symbian Foundation, which will be an independent force for the future development of Symbian OS. They stated that Symbian OS (including the platforms S60, UIQ and MOAP(S)) will become open source in the first half of 2009
