Marius Masalar asks the question of which input device is easier to use. His own answer? Both.
My usage is by no means exclusively as described above, but in general if I’m moving a cursor and clicking, it’s with the mouse, and if I’m navigating a canvas or scrolling, it’s with the trackpad.
Personally, with a trackpad on one machine (my main laptop) and Magic Mouse on another (our family laptop), there’s no comparison. I’ll take a trackpad 100% of the time. All the pain I used to experience in daily computer use went out the window once I switched to a trackpad.
Now, whether that’s due to mice being so bad, or just the Magic Mouse being so bad, I’m not sure.
