A little outdated article about Symbian OS. History doesn't mention open sourcing and introduction doesn't mention UIQ is discontinued and what's a infrared port? ;).
I learnt that Fujitsu have its own ui for Symbian. I don't remember seeing it on Wikipedia when I was last reading about Symbian (I'm quite new to this OS).--22:50, 5 September 2009 (UTC)
This article mainly deals with the key features and architecture of Symbian Operating System. The key features like multi-tasking, used in limited memory and battery devices, efficient memory management are metioned in ths article. These features make Symbian OS more efficient and powerful than other operating systems. The simple architecture of the Symbian OS is also illustrated. Though this article has not described the points in details but the abstraction of key points is good.
This article can be useful to beginners only.
