Well, as there&#x27;s no Cocoa on Windows and no WPF on OS X it doesn&#x27;t really matter.<p>Also that SO post reads a lot like &quot;I can&#x27;t stand Interface Builder&quot; (which is understandable if you aren&#x27;t prepare to embrace it).<p>I find the Cocoa model of not having to do anything with XML far better for my sanity. But then again I guess there are people who prefer XML artistry to drawRect overriding. :)
