Wifi/Cable syncing of a desktop and phone app is a completely different beast to doing so over the internet. The difference is that when you connect your iphone to your laptop and sync, the app determines which one has the last state and updates accordingly. Over the air syncing would imply the possibility of different mediums having different states and having to consolidate all the data into a definite final state, preferably by updating, deleting, or creating single objects instead of a complete store of the data. Trust me, it's not that easy and lot's of implementations done already on other apps are not quality implementations. Actually a lot of implementations are really a hack plugged in to deliver the functionality asap. That being said, it's not something that should take two years in the making. Nevertheless, Things is already a great application in it's current state and well worth the money.
