With each new HTML5 demo of something that comes up, I get the sneaking suspicion that HTML5 adoption is going to be slow.<p>It seems the capabilities of HTML5 and what you can do with it from an application basis are fine and dandy. It's just my observation and very-limited experience, but I've yet to see anything that really knocks it out of the park for me.<p>I'm currently working on a project that relies heavily on client-side javascript and flash (for media delivery). We have spent some time evaluating HTML5 and whether we should "cut the cord" and move to developing for that basis.<p>At this point, we've determined it makes no sense to do so for one simple reason -- it offers us no valued advantage over our current investment. While we hope to see the adoption improve, we're not holding our collective breath.
