I had a 23" Apple Cinema Display and, tell you what, it was useless since the default res, ie. the only one with any clarity, was 1600x1200 with everything half the normal viewing size. The advantage of all the Quartz Extreme rendering was completely lost since the anti-aliasing looked fuzzy at such a high res. Apparently video editors prefer this setup but for webdev I had to send it back. The replacement Formac Gallery 1900 is much better (and less than half the price) with a default 1280x1024.
