The Hawkeye System

In the past, whether it's professional or amateur tennis, there has been many controversies and conflicts between the two players on whether the ball had landed in (landing on the line is called in) or out.
In the quarter finals of the US Open 2004, Serena Williams had many calls against her leading to her defeat, more because of the calls of the umpire than the pressure of her opponent, Jennifer Capriati. This was a large controversy that caused officials to bring in a new system called the Hawkeye System.
It would determine whether the ball was out using different cameras from different places of the arena. All you had to do was "challenge" the call of a linesman or umpire if you thought their call was wrong. However you couldn't argue with the result of the Hawkeye and this is a problem because officials say that this system is not 100% accurate. but, it is a much better way to solve conflicts, in my opinion.

So, do you think the Hawkeye system should be taken away until it is closer to 100% accurate or kept? Why would keeping this system cause a problem?
