Addicted to upgrades, yes, but sometimes it isn't really worth it. Case in point: Microsoft Word 2000, and a feature that has become even more problematic: saving as HTML. Word 97 had the reputation of producing poor HTML which could not be "round-tripped" back into Word. Word 2000 addresses this by saving HTML with very significant XML and CSS mark-up that preserves all document formatting, metadata and structure. The disadvantage of this is that for usual Web publishing Word HTML files are far heavier than is really necessary, filled with information you may not want or need to share, and XML tags which actually do not do anything. An optional HTML export filter that can be downloaded from the Microsoft site produces somewhat cleaner code, but is only a half-measure: Word should allow the user to choose HTML that is compatible with older 3.0 browsers, even if formatting is lost.
