Friends,
First, let none doubt my loyalty to Logos! If you *** me, do I not bleed blue? 
Having said that, a conference speaker I like recently wrote a comparison between Logos 4 and WS 9. His comments are insightful and mostly complimentary to Logos. I'd like to publish them here in this forum, but figure there may be policies (written or otherwise) that discourage discussion of the, uh, competition. I thought I'd ask permission in advance instead of forgiveness later! I do have the author's go ahead to reprint his review.
Thanks,
Steve
P.S. Wow! I was surprised when the forum software edited the first sentence of my post! I've never been censored before. Shakespeare is chagrined.
