X is fine in my opinion. It's flexible and a known commodity with pretty good hardware support. The cost (in man hours) of replacing X and modifying all the associated bits that rely on it far out weighs NVIDIA or ATI getting someone to spend a few hours developing a utility to setup multiple monitors. A lot of the things people blame on X really have very little or nothing to do with it.
