Is reconfiguring the very shape of the plane in mid flight all that "simple"? How do things going wrong here compare to things going wrong with the shuttle? Does this have more robust failure modes?
There are less moving parts (or at least systems) than the shuttle. And the simple may also refer to what it's like for the pilot (process). From what I understand, it's a hands-free re-entry, and more comfortable than a capsule because it's more predictable and slower.
