I understand your concern about the response time of the various Apple LCD Displays, but don't forget that there's probably a reason for it to be around 14ms, bearing in mind that a lot of displays which have very low response times tend to have downsides such as poor 'actual' viewing angles (I've used a few displays which claimed 170 degree viewing angles, but the colours were badly shifted as soon as you moved your head either side of centre!).
