Sometimes, you need out because any other solution would be unwieldy. For example, look at TryParse and TryParseExact:
C#
public static bool TryParse(string s, out int result)
The difference between Convert.ToInt32 and Int32.TryParse is that the former throws an exception, the later returns an OK / Fail result - and needs the out parameter in order to return the value as well.
While you could use Convert instead, and wrap it with a try...catch block to get the same effect, using exceptions as part of normal processing is an anathema to me (and is rather ugly). And user input checking is (or should damn well be) part of normal processing.
You could create a Generic type which contains the value and a bool but that's ugly and annoying as well.

One out or ref for good reason is OK - if it starts to get more than that, then probably it needs a class or struct instead.

And I do find the "using out and ref requires an understanding of pointers" a bit specious as well: if you don't understand them, then I suspect that an out parameter is the least of your problems! Laugh | :laugh:
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...
