What does "taking it seriously" have to do with whether you play on desktop or laptop? Most people I know already need to use a laptop of some kind on a daily basis for work or school and there are plenty of mid-range laptops available that will run most games at 1080p without costing an arm and a leg. And you can still use a mouse, you don't need to game with the touchpad.
