ANDROID

Albert einstien spoke about a theory of "everything".A theory that will define and describe ...well, everything (which also includes nothing,the theory will also describe "nothing". i.e vacuum)
How far or How near we are to this theory is debatable.Scientists have been working on it for decades without any real success , but we can never tell when the next eureka moment comes.
Any ways, you ask what has this got to do with ANDROID (if you already know what Android is)

ANDROID is, a kind of , googles (and a few other companies ) , idea of a theory of everything. In simple words it's a platform for mobile communication devices which is hardware independent.
it'll work on a nokia , a SE , a sagem etc etc. It's an open sourced mobile OS. Android will deliver a complete set of software for mobile devices:
an operating system, middleware and key mobile applications.

Open

Android was built from the ground-up to enable developers to create compelling mobile applications that take full advantage of all a handset has to offer. It is built to be truly open. For example, an application could call upon any of the phone's core functionality such as making calls, sending text messages, or using the camera, allowing developers to create richer and more cohesive experiences for users. Android is built on the open Linux Kernel. Furthermore, it utilizes a custom virtual machine that has been designed to optimize memory and hardware resources in a mobile environment. Android will be open source; it can be liberally extended to incorporate new cutting edge technologies as they emerge. The platform will continue to evolve as the developer community works together to build innovative mobile applications.

All applications are created equal

Android does not differentiate between the phone's core applications and third-party applications. They can all be built to have equal access to a phone's capabilities providing users with a broad spectrum If applications and services. With devices built on the Android Platform, users will be able to fully tailor the phone to their interests. They can swap out the phone's homescreen, the style of the dialer, or any of the applications. They can even instruct their phones to use their favorite photo viewing application to handle the viewing of all photos.

Breaking down application boundaries
Android breaks down the barriers to building new and innovative applications. For example, a developer can combine information from the web with data on an individual's mobile phone -- such as the user's contacts, calendar, or geographic location -- to provide a more relevant user experience. With Android, a developer could build an application that enables users to view the location of their friends and be alerted when they are in the vicinity giving them a chance to connect.

Fast & easy application development
Android provides access to a wide range of useful libraries and tools
that can be used to build rich applications. For example, Android
enables developers to obtain the location of the device, and allows
devices to communicate with one another enabling rich peer-to-peer
social applications. In addition, Android includes a full set of tools
that have been built from the ground up alongside the platform
providing developers with high productivity and deep insight into their
applications.

"Today's announcement is more ambitious than any single 'Google Phone'
that the press has been speculating about over the past few weeks. Our
vision is that the powerful platform we're unveiling will power
thousands of different phone models."

-Eric Schmidt, Google Chairman/CEO , after announcing the Android .

This is how the framework of a general Android enabled device will look like:
