Imagining a window-less user friendly operating system
I believe all of us are used to thinking operating systems in a 'window' based environment. Each operating system viz. Windows, OSX, uBuntu and others are typically window-based; meaning, they provide you with various graphic boxes [windows] to work in.
If you wish to browse the Internet, you must open a new window - that is, your web browser. If you want to type some text, you must open another window - your text editor.
I'm thinking, why should we be limited to a window-based GUI. Can there be something entirely different?
Can you extend this idea further?
