Google can help you out with more information if you are truly interested in reading up on it all.

In that case, Pitch F/X will have a higher percentage of pitches measured incorrectly. That number may only be 1-2% more than something more accurate, but it will be higher. For it's current application, it doesn't matter if it's "not good enough". The inaccuracy applies equally to all umpires, and its output should be viewed only as a relative comparison between different umpire's ball/strike accuracy. I doubt it would be suitable to replace the role of an umpire. I'd at least need a bit more convincing.
For what it's worth, the Pitch F/X setup is much less complex and probably costs 20% of what I suggested above. It's diminishing returns, and it all depends on how accurate you need the measurement to be. An inch will cost you millions...
