Thanks for the input everyone. If I go with a 7" instead, what functions would I be missing out on? If it's pitch location, I don't need that. What else?
You won't miss any functionality, it's just more difficult to use on a smaller screen due to the level of detail. There is a lot of text in iScore, and it's just harder to read on a smaller screen. Like I said, my iPad mini (7.9") is adequate for iScore, but I wouldn't consider smaller for that app. JMHO, YMMV and all that!
