<i>So I think your point, while valid, does not apply in any way to Xamarin!</i><p>I&#x27;ll believe it when I see it. Cross-platform UI libraries like Qt, Gtk, SWT, etc, just never end up choosing quite the right widgets or having exactly the right look-and-feel as natively-designed apps.<p>If cross-platform is a bigger requirement than producing the best-possible UX, then perhaps Xamarin could deliver. I see this being a big deal with enterprise software. But that&#x27;s almost never the case for most consumer-facing software; you&#x27;re always much, much better off building your presentation code in a native UI toolkit.
