(OP as well)
It is not clear from your website what type of applications you have developed so far for iOS which make it hard to "judge" your choice whether or not you were right about choosing native over HTML5.
But I wish to remind us all that those two can, and in many cases should be combined.
If we take Google iPad suite or Twitter formal client, they are iOS apps which render content through the webkit object.
If your app deals with data which resides on the web, and with loads of it, perhaps rendering the presentation layer in HTML5 is not a bad choice as your "elite-ios-wiling-to-pay" customers are indifference about it, while at the same time, you can win the other market (Android).
