Article about the benefits of Qt4 over Qt3?

I would advise you to look for news about the release of Qt4.0, there's certainly a detailed description of why Qt4 is better. And in General: Qt4 faster, more functional Qt4, Qt4 has a normal port on Windows, Qt4 is much more krossplatformena, develops Qt4, but in Qt3 even bugs, not a rule.
