And to reiterate, I think Accordance is a wonderful program, and I truly appreciate the hard work the folks have put into making this program so powerful and easy to use.
I have actually used all three of the major programs, and they each have their strengths. I still have BibleWorks installed in Parallels on my MacBook, but I only rarely fire it up to use some resource I already own there but do not have in Accordance. On the whole, given the complexity inherent in the power the programs possess, it is hard enough to learn all the things you can do with any one of them - much less to keep switching between them all.
It is great to have these tools available today. What a gift to those of us wanting to study, apply, and teach God's Word!
