What is Google Android?

Google Android has been developed by the Open Handset Alliance and intendes to make using your mobile appliance more like using the internet

Android is built from the ground up as an open source operating system. This means that any application can call on all the phones resources during its operation: sending text messages, making calls, using the camera, etc, etc. This allows for the applications to be far richer than has been possible in the past whereas the negatives are that a badly programmed application could reduce your phones performance.
