I don't know why you are such on the defensive, I just said it's fine to prefer one over the other. I shared an opinion, not a fact (and so did you). You are not the only one doing 'real' productivity, and my point was not related to gimmicky features, but real efficiency improvement when using the trackpad over the mouse. I do find it better for my own workflow, which includes notably spreadsheets, multitasking, video production and documentation.Less efficient & natural doing what? You name it.
I'm talking about real productivity (as in media editing, layer based post production, vector & graphics manipulation, coding, multitasking, documentation, spreadsheets, DBs, 3D modelling, intense browser navigation, inspecting & debugging, etc).
Please don't tell me banal stuff like "pinching to zoom". Also, it's totally fine to prefer either one. Just saying that productivity speed & efficiency isn't necessarily a result of "feels nice" emotions.
But I will state it again so you don't feel attacked, my experience is not the one that everyone here should have, you might find the Magic Mouse as a better tool for your workflow and it's totally fine.
