Modernizr returns Webkit in Opera Mobile Emulator Experimental. If webkit and opera work the same then this doesn't matter. However, if you want to avoid bugs such as this: http://jsfiddle.net/ianlunn/76Les/ you can't serve a workaround for Opera because you can no longer safely determine the browser is Opera. You'd have to browser sniff instead, not good!
JavaScript
alert(Modernizr.prefixed('transition'));
