Some of my most beloved products are those that make ME amazing at something that matters to me, even if I am kicking and screaming and swearing at the product while using it. Of course if I am kicking and screaming and swearing, I’m obviously having a compromised experience… One that might prevent me from producing something wonderful. But I’ll still take a poor UX that makes me truly better at something I care about, than the beautiful, artful, exquisite “Who Cares” product.
