The Conditional Operator

Great book! I tried Obj-C 6 months ago with an O'Reilly book and it was just too obtuse. This text, however, is working out great for me.
Anyhow, perhaps this is premature, but I'd be interested in knowing why the "conditional operator" device/syntax is more useful than just running if/then statements. Clearly there's more to come in later chapters but can anyone summerize thoughts on it's value? I suppose it's more concise but, in that, less easily readable IMO.
Thoughts?

It took me a while to appreciate it too, but now I think it's pretty cool if you have a very short and simple If/Then/Else expression to evaluate. Anything more than that I'd always go for the longhand version.
I'm up to chapter 12 and I can see how the conditional operator becomes handy when you start getting into Macros (see examples page 245).
Cheers,
Ben

Yes, because it's an operator and not a statement, it can be used in places where an if/else can't. As noted by Ben, macros are a perfect case in point.
