I found Appendix A5 rather amusing...it is their defense of inserting the name "Jehovah" into the Greek Scriptures something like 230+ times. Their arguement was underwhelming at best.
That being said, I was pretty impressed at the Apple version of the app. Being able to touch the verse in the NNWT and have ~5 different translations of that verse (including the Greek Interlinear) appear right next to it is pretty freakin' cool.
Edit: I had to laugh when the brother walked through all the apps/devices. It felt like the Apple developers conference in SF. He should have been wearing black jean and black turtleneck!
