Having developed in .NET and Objective-C I think they are both pretty much the same (.NEt might be a little faster, but not much). However, if you've already got .NET programmers then it's going to be a lot faster than having to train them up in Objective-C, which does take a little bit of a mind-shift.
I think where this really comes into play is now there are literally armies of iPhone developers in India and elsewhere (where there are lots of .NET programmers). The cost of iPhone app development should come down considerably.
