I'd say it depends more on app type than on HTML5 progress. For apps what are little more than glorified content viewers HTML is promising, for others — not so much. HTML5 brings some sanity and improvements, but at the roots it is still same old and lame HTML. You may spin and twist it, but at the end the question is "was it worth is". And the answer, most often than not is "hardly". Improving hardware won't change that, at least not substantially.
