I came across this post on engadget that really illustrates the potential of FOSS. It opens up a world of infinite possibilities. This is one of the main reasons for which I love Android more than iOS or Windows Phone. In the two latter cases, you cannot go beyond a certain limit due to the ‘closed source’ ness of these mobile operating systems. Even though Android too isn’t completely open sourced, it still beats the latter operating systems. The things you can do with an Android device are infinite.
