Things touch 1.1 now supports syncing with its desktop counterpart. This is the update I was waiting for, so last night I pulled the trigger and purchased the app.
So far I’m very impressed. The sync feature requires that both the desktop and iPhone be on the same network – which is fine with me. The setup and continued usage is so seamless and simple that it makes me question why in the world we don’t have this feature with iTunes and “information” data.
Overall the Things experience is very pleasant and feels very Apple-like; much more so than OmniFocus.
If you’re looking for a GTD solution, take a look at the Things suite.
