True that the resources for Windows apps can all reside in a single directory, but Mac OS wins because it enforced a more consistent standard with treating app bundles as self-contained applications and encouraging Mac developers to follow that example, which has yielded a more consistent user experience when installing and removing apps. Windows developers have had too many installation strategies to choose from, with little help from Microsoft (Microsoft once offered a weak setup toolkit on MSDN but Windows never really had a consistent built-in app installation API, not even a simple copyfile() function was provided by the OS) and thus every Windows app install and remove process is entirely different, there's even a market for competing app install toolkits in Windows, which describes the overall user experience in Windows: inconsistent.
