I do all of what you describe and I also need a mouse with windows laptops - but not because touchpads are bad in general, it's just that windows laptops have absolutely rubbish ones compared to Macbooks. A precision pointer device right below my thumb is still the most productive way to make the cursor go to a specific point on the screen - it's the only way to reduce that particular action down to one gesture in the general case. Hotkeys and macros only help in special cases. Doing computing today basically results in a series of little 1D problems and 2D problems. Sometimes the keyboard, which creates a 1D stream of input sequences, maps well to a 2D problem, but very often using an actual 2D device is the most efficient way of dealing with that.
