Lest anyone think I am prejudiced against SP2...

I reckon they should read http://www.unixwiz.net/techtips/xp-sp2.html very closely and understand the tremedous potential benefits of what MS is trying to achieve. SP2 is an impressive package: my argument is soley against the way it is rolled out.

According to the official bad apps knowledge base article 200 proper apps are on the list. That is 200 apps that MS thought would be at risk. My guess is by the time SP2 is history that number could rise to 2000. Some will be small and trvial, but my guess also is that almost every Windows developer will need to take account of Sp2 - just to stand still.
