Getting Snow Leopard today? Then you will probably want to know which applications will work with your fresh OS. Snow Leopard will automatically move your incompatible applications into a separate folder, as well as prevent incompatible software from launching until they are updated.
There is an official compatibility list here by Apple, however there is a more robust wiki available that catalogues a ton of applications.
