I interviewed at Parke-Davis last Tuesday and was given a demo of Insight II
and Sybyl by Tripos in St. Louis. Personally I think the interface on
Insight II is more "user friendly" than Sybyl. The demonstrator prefered Sybyl
as being to build up structures with. Tripos has been around the longest of
the computational chemistry software companies and is probably the most
stable. I believe they are owned by Evans and Sutherland.
