Mood: lazy
I see pictures on Lycos home page of people laying on sofas typing on their laptop computers. Try that. It is not something that you will find to be comfortable and you can't really get much done in that position.
Unless your keyboard is very small and you find it easy to navigate the Internet before your shoulders ache and your hands go to sleep, you will end up changing position and sitting up, Indian style or at you desk.
Laptop computers -- when is the last time you actually saw someone with one sitting on their lap? It is not convenient nor comfortable.
