"Android" by google

Yesterday, T-mobile announced their new product. It is an intelligent cell phone, named "G1". T-mobile is one of the mobile phone companies in the USA. of course, many mobile phone companies often released a lot of their products. But G1 is a different from them. They adopted "Android" for this product’s operating system. "Android" is developed by Google that is a famous Internet searching engine company.

Operating system is basic system software for computer. It controls all software on computer and every software takes advantage of the functions in operating system. Many type of intelligent cell phone has such an operating system also.

Google has been developing an operating system for mobile phone. Furthermore they open the source code of it. Source code is rewritable original code of software by programming language. If software developers get such source codes, they can read all this technology from it and use it for free. Any mobile phone makers can implement "Android" on their product freely.
This idea is called "open source approach" in software industry. It is a kind of policy. Someone who takes this policy opens his source code, then someone else can use this source code but he have to open his new source code. They are developing each other with their codes in common. Google has been developing "Android" with such source codes, so they want to open the source code of "Android".

Usual businesses proceed with being depended on their own specialty. So almost software developing company close their technology and they want have their uniqueness. But the idea of "open source approach" is quite different. They want to have creative solutions efficiently with using their resources each other and want to make creative combinations of their resources.

Our global world has a lot of intelligent resources. If all of them were opened and we could use them freely, we might be able to create a lot of things more efficiently. But most of people don’t allow it, because they think they have profits of rights of their own resources. Therefore open source approach might be able to change a social situation. So I think that ‘G1’ is very interesting product.
