Guess I never paid much attention to what data was on my first gen iPad as I had 64 GB. My new iPad2 has 16GB, so I am paying a bit more attention to available space. When I did the sync I was watching the bar at the bottom, showed like 3.36GB for videos; maybe 5 GB for Apps; 1.10 GB for photos: and like 4.4 GB other. Leaving me with like 3.4 - 4.4 GB free. What does the "other" comprise of? Thanks.
