A while back there was a news item in _Science_ about how Leland Wilkinson
of Systat accused the folks at StatSoft of stealing some of his
algorithms from Systat.  I think there was also some news about
Statistica producing incorrect results for some analyses, though that
may have been fixed in subsequent releases.  It was always my
impression that Wilkinson was a real standup guy and that he wouldn't
accuse someone of something so serious without strong evidence, so my
personal decision would be to stay away from Statistica.  Your mileage
may vary, however.

I have been very happy with StatView and SuperANOVA on the Macintosh.
Both have very nice interfaces, and SuperANOVA is by far the easiest
way to do ANOVA that I have seen.  The new version of StatView is
native for PowerMac and is very fast, while SuperANOVA has not yet
been released in a native version.  I heard rumors a while back that
SuperANOVA might become a plug-in module for StatView, but no
corroboration has arisen for that.  Both of these packages have
flexible transformation options and can deal with large data sets.
