Offline syncing is tough, but it's hardly an unsolved problem in the world of software. It's not even an unsolved problem in their specific market: syncing a todo list between the iPhone, iPad, and Mac OS X.

I'm not a Things user, but I'd be pretty annoyed if after two years the only thing they've said is "it's really hard" and the actual feature is still months away.

There are two major mistakes here:

This smacks of massive over-engineering to me. Cloud syncing is one of those problems where the type of data you are syncing significantly affects how you approach the problem. In my experience, generalized components are not very useful here, since you need to custom tailor the sync based on your specific use case anyway.

I suspect they're now going to run into problems while mapping their generalized solution to their use case. And since there is only one use case to support in the first place, it won't have accomplished much except wasting a bunch of time.

Do they actually have a million users to support? I doubt it, given the relatively high price tag of Things on the iPhone/iPad/Mac ($9.99/$19.99/$49.95). If they did, they would have several million dollars to throw at the problem. This certainly seems like a case of premature optimization.

Judging by the comments here (and in the original blog post), in the amount of time they've spent trying to build the perfect, scalable sync framework, they've hemorrhaged a vast portion of their customer base to other apps like OmniFocus (despite the fact that OmniFocus is significantly more expensive).

Too late for this ex-Things user, unfortunately. I waited for over a year before switching to OmniFocus. After buying licenses and climbing OF's relatively steep learning curve, I'm too invested to switch back.

Two years and all I got was this stupid blog post.

I and every Things user I know of has switched to (and love) OmniFocus. It has sync and works now, not months from now.

I jumped the ship and switched to RTM for syncing alone.

Now I just type in shopping list on my laptop and when I come to grocery store, it's in my iPhone. Feels good man!

If anyone wants a Things license let me know. I'm out.
