Getting low on space triggers more aggressive cleaning, so 8GB and 16GB iPhone users will suffer before those with more storage. But if you read files in the subway, or other areas without network access, you may soon tap on an unpleasantly clean folder.
So much for Maps on the iPod Touch. This is not good news.

Every year before I go on vacation (to somewhere where Wi-fi is dicey at best) I load up my iPhone with podcasts to listen to. If I show up at my destination and find out that they've been deleted because I decided to download a song while waiting at the airport... I. Will. Be. Pissed.

What part of "cache" or "tmp" suggest "persistent storage that doesn't get deleted when space is needed for other things."

Simply don't sync too much onto your device and you will not run into this issue. Leave a few gigs free after you sync and you should be fine.
