THINGS is a not-yet-shipped desktop OS X task manager with lightweight project management. Things touch is a current iPhone App.
So far, mildly interesting. There's no mention on the web site of data export capabilities, so they probably fail the data freedom test.
The interesting news is that they claim to have a sync solution coming soon, and they give us a workaround for the very nasty data loss (this is Apple, they live to kill data) problem associated with iPhone App updates: Things touch 1.0.1, Syncing, and How to Prevent Data Losses When Updating iPhone Apps.
I wonder how they do the sync -- there's been little mention anywhere of how developers can sync across the conduit. I wonder if they're using some kind of file share sync.
