The problem with Hawk Eye is the way it is actually applied to cricket (which is different to its use in any other sports), and all this stuff about used by the military (great) but it doesn't actually address this main problem.
Not a lot of people seem to understand how Hawk Eye is used in practice. At a match where it is being used there will be some guy in one of the broadcast vans operating Hawk Eye. What is it that he has to do? Well, he has to decide at which point the ball hits the batsman and at that point (via the press of a button, I assume) the predicative element takes over. But the number of times one watches on the TV and disagrees with where the so-called first point of impact was, leads me to severely question how accurate this man-in-the-van is (and at the end of the day, it's just as open to human error). Interestingly it also explains sometimes why you see rewinds of the footage being done if Hawk Eye is cut to pretty quickly after the decision (as the man-in-the-van is trying to work out where and when to push the button).
It's this human element of Hawk Eye's application in cricket which is distinct from how it is used in other sports (e.g. tennis) when it is much more akin to how Hawk Eye works when dealing with where did the ball pitch (for which I think Hawk Eye is great).
Next match you watch with Hawk Eye in, look at for where they suggest the first point of impact is; I bet you'll disagree at least once (if not a fair few more times!).
