I prefer to write applications in a mix of C, Scheme/Lisp, or Haskell. I can probably write faster and more stable iPhone apps with these tools than a 10-man-strong team can with C and Objective-C.
Have you?
Have you?
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?
