What makes you say "the one area"? There are plenty of areas that have enough development friction / inertia such that the same principle applies. Even generally, I think the reason why people caution against reinventing the wheel isn't because it prevents innovation, but because it wastes time / incurs additional risk.

I agree with you. When I read that my first thought was "the one area"? Personally I think its the complete opposite, like really strongly. like really really strongly. I'm certain for at least 10 years now, once a week I think "I miss old desktop operating systems". Any of them. 7,vista,xp. snow leopard,leopard,tiger. I even stopped using Ubuntu when it went from Gnome 2 to Gnome 3 and other options at that time were pretty bad so I ended up getting back into mac's for my home desktop. I still use all 3 daily, but hate all of them.
