I totally agree and we can name a lot of apps... people, use the software before criticizing!

IMHO yes, there are some OS X apps that are very good in usability but there are a lot of exceptions:

Banshee > iTunes Gnome-do > Quicksilver (even though this is not from Apple) Nautilus > Finder (yes this is very true)

I'm not even mentioning the apps that just don't exist in OS X: a real multi-desktop, Tomboy (even though there is a port), a real app manager.
