I came across this interesting quiz on Duet. It tells you a lot of facts about Duet that are sometimes glossed over in sales colleterals and demos. There are some interesting ones as well.
Just to share - I got 8 out of the 10 questions right! Duet-watcher as I am, I still discovered a few things. Like I did not know that Duet required 1G of disk space.
Well well, we live and learn, don't we?
