InDesign is reputedly very good, but it's hard to argue that the Adobe PDF reader is equally good - it's bloated, full of security problems, etcetera.<p>Similarly, Adobe's Flash design tools may be cool; but the Flash client sucks. The anti-Flash sentiment wouldn't be quite as prominent if there were a decent, lightweight open-source Flash player that ran well everywhere. (Of course, the semantic web people would still hate Flash.)
