I consider the gold standard of file browsers to be the one the pro-NeXT+Cocoa/anti-Carbon camp swore on Jesus' grave that would vastly exceed and suck less than the Carbon one once Apple finally rewrote it entirely in Cocoa. Well that happened and yet there's been essentially no change. It still hangs and spins a beachball when a network is disconnected, it's still gets confused what icons to use, and duplicate app icons in contextual launch menus, on and on, it's like - yeah it's not a Cocoa vs Carbon thing, can we admit that now?
