Can you probably, or have you actually build in shorter time (or did you really mean apps that run faster) apps that are more stable than that created by a 10-man strong Obj-C team for the iPhone?

If so, would you say it was a function of the quality of the other programmers, or could it be distilled to purely tools?

Genuine interest (since I love languages for their own sake and the expressiveness they allow): what tools + languages did you use?

We should just take your word for it?
