Ideally, you need to have both a PPC and an Intel Mac to ensure that your programs work on both platforms, as this isn't necessarily the case. Just because it compiled, doesn't mean it will run. Of course, the communtity will always be able to test for you, but I'd prefer to be able to test myself as well, as it's then quicker to make any changes.
