But you haven't described how to uninstall an app. You described how to remove the program directory, which would be the same as deleting the folder in Program File on windows.

Changes to system config won't be rolled back and other files won't be cleaned up.

That's why on Mac OS you sometimes have to get an uninstaller, which sucks because now you have an inconsistency.

These didn't exist on the original Macs[0], and I would argue that they shouldn't exist on any Desktop OS.

[0] Unless you count Extensions, which were still drag-and-drop but to a special folder under System.

From the UI standpoint proper uninstalling can be tied to deleting the app.

Otherwise a user-level app only used to have a preferences folder and uninstalling an app should not delete the preferences -- maybe you'll reinstall it later. Or at least it should ask for it.
