CD-rs do not have a coating over the data, so they naturally have a shorter lifespan and will not take abuse without scratching the data layer.
That said, I have cdrs which were burned 10 years ago and play fine.
I'm not saying everyone will get the same mileage - but I am saying I've been burning for a long time and have yet to see ANY disc deterioration.
