Query: I'll stick with ACT V6

After having done a quick trial and then read the comments of many other people, I'll gonna stick with the previous version - even though I'm not truly impressed with that one:I think that the major drawback is the fact, the the underlying data structure is not a true relational DB. That makes it pretty hard for developers to overcome this restriction in the application itself. Long time ago, I had something that I developed on my own; it didn't have all the bells and whistles ACT has, but it was based on a true relational database. That made it easy to come up with different views, to maintain hierarchies (such as contact --> company --> belongs to company).There were also some reviews that pointed out that 10,000 contacts are a lot - say too much for ACT. Well, I think that every contact management system such be perfectly able to deal with this 'huge' number ;-)
