Siemens dumps Symbian
November 09, 2005 [General]
During a press conference yesterday representatives of Siemens Mobile (now owned by BenQ) have confirmed:
... that they are not interested in further development of smartphones based on Symbian operating system. Instead they will be producing and selling phones based only on Microsoft's Windows Mobile. Of course Siemens Mobile / BenQ will be producing also phones based on proprietary (non-smartphone based, closed) operating systems, but as far as smartphones are concerned: only such that will be based on Windows Mobile! The first one will be Siemens P50 (formerly known as BenQ P50) but more is coming.
There are many reasons why it is bad business decision for mobile phone manufacturers to make Symbian phones but among top reasons may be: a) fact that given manufacturer must compete with Nokia on Nokia's terms and since Nokia spends millions of USD on marketing, such competing can't succeed - it is like fighting fire with fire - it simply doesn't work and one needs to fight fire with water and one needs to use Windows Mobile! ... or b) fact that by using Symbian one is directly supporting main competitor.
Please note also that although Samsung has not dumped Symbian yet, it is producing its most advanced (Wi-Fi, hard disks) smartphones only with Windows Mobile. On the other hand Palm has clearly denied that it will pick Symbian for upcoming Treos. Increasingly phone vendors are realizing that Symbian is bad idea. Bad business decision.
我同意这篇文章对原因的分析。没错，去年Nokia收购Psion的股份以后，已经持有Symbian超过60%的股份——事实上，Symbian就是Nokia的。
Psion告别Symbian了，摩托罗拉彻底告别Symbian了，西门子彻底告别Symbian了。在剩下的还开发基于Symbian的手机厂商里，有份量的只剩下诺基亚、索尼爱立信和三星了（松下、LG、联想等都份额太小）。
三星脚踏几条船，同时还在做Windows Mobile和Palm的智能手机，Symbian的新机越出越少。只剩下索尼爱立信还跟着诺基亚在干......我猜，要不了一两年，索尼爱立信就会像今年年初索尼抛弃Palm一样抛弃诺基亚。
索尼总是扮演往棺材上钉最后一根钉子的角色。
