I will never say that Windows is better than Linux, but that doesn't mean that Linux doesn't change stuff out with little ramification. They might decide to swap out the RAID system tomorrow with a completely new interface. Just because they haven't yet doesn't mean they won't, and their track record doesn't inspire confidence.

That doesn't mean that any of the things they've swapped out or the things they've replaced them with are bad, just that they constantly change, and if a concern is the ability to reproduce, that might be a significant legitimate concern.
