One of the very strange things about software companies is that they love to tell us how wonderful their software is now, but then later they tell us how terrible that same software is, when the new version comes out. For example, I am sure that back in 1999 the SAS marketing people were eloquent on the wonders of SAS Version 8, but today they are equally eloquent on why Version 8 is terrible, and needs to be replaced immediately by Version 9. Oh, well.
