I have the same experiences. We wrote http://hyves.nl/hybrid http://hyves.nl/hybrid which works wonderfully on iOS. But didnt really deliver the HTML promise on Android. Maybe because of the browser which was not as good as the safari a year ago. And maybe also because of slower phones. However the same code did run on iOS blackberry and Android. However the experience was sub-native on most devices. And we really needed to do a lot of tweaking and work to get the native look and feel on iOS. So if you want to be the best, no matter the costs, go native. Otherwise Sencha is not a bad choice to make. It really depends on your requirements.
