iPad 2, 16GB wifi, running 4.3.3. I've been gradually watching my storage space drop by about 100MB per day for the last week or so. I'm down from 9.0GB to 7.9GB without adding any new apps or any substantial files stored locally. I run 26 apps, none of which are huge space hogs. Two games for the kids, no music, no movies. Most all of my apps and files are business related. Lots of .pdf documents and a handful of small Keynote presentations. Dropbox set to store a mere 200MB locally. Goodreader is syncing about 360MB from cloud storage. Cache cleared in browsers regularly. iTunes breaks down my storage as 0.01GB photos, 0.01GB books, 0.45GB other, and 5.3GB apps. Any ideas?
