My feeling is that these fantastic assumptions of HTML5 being the best thing since sliced bread and trumping all the benefits of native support assume a vacuum and lack of innovation in the native client space. Even in this vacuum, HTML5 browsers and embedded views have a long ways to go before they can compete with current native feature support, performance, etc. from a consumer's perspective as far as I am concerned.<p>I have a strong desire to see more HTML5 based applications going forward, but I do not see them overtaking or marginalizing native applications in any substantial way within 2-5 years. I also feel we can obviously expect many developments, improvements, and features to evolve in the native application space that will create further incentives to produce native implementations and that we can not assume that HTML5 implementations will be able to keep pace with them.
