I think Gruber would elaborate by mentioning that garbage collection has a real and measurable cost in terms of performance and Apple would rather have a development environment that allows devs to produce the smoothest UI performance over one like Java or C# that is novice friendly but harder to get the highest level of performance out of. Personally I really enjoy working in Objective-C and Cocoa/Cocoa Touch. I think they both hit sweet spots in language/framework design and give you just enough high level abstractions to make developing easier without getting in the way. But then again, I program in C for fun :-)
