Indeed, InDesign is becoming so popular especially among designers. There have also been plenty of newspapers or publications going the InDesign way and the most common answer given by those I have asked was because of the restrictive cost of getting a Quark license and the poor support. On the other hand, Adobe had been giving good offers, including the killer IDCS offer. As for print bureaus, many of those I've met, including some in the Middle East, say while most of the jobs they get were made in Quark, they had to get their own copies of InDesign because they were experiencing a steady increase in InDesign files.
Oh, well, it may still not be too late. Quark 6 packaged with Macromedia MX is a lot better offer but will Quark do more? It would be good to know.
