I think there is a small bug in the survey. The 2nd question requires an answer, but starts with 'If 'Yes'...' to the previous. What if the 1st question was answered with 'No'? How can you require an answer to an 'If yes' question in that case? The rest of the survey may still provide valuable data to you.
For those unfamiliar with the expo/dev software, please see how it works on a palm pilot on our instructional videos on youtube.com. To find the videos please do a search with the word "viewcamerastore". The information would be helpful for our programer, as we have had requests for the expo/dev software on an iphone and other more modern devices.
