I would like to use my macbook pro using its touchpad. Just to relax my hand! I know, almost all of us use the mouse. I wonder, how could I leave the mouse and use only touchpad. I have to work in many applications, word, excel, photoshop, dreamweaver etc. Is it practical? Is it fast? Can we live without mouses? Any advice in case I start to use touchpad? What should I know, what should I avoid?
