This doesn't look very unbiased. It shows the "HTML5" version being slow in terms of scrolling through a page, clicking on a tab, and using a slider. Most websites, even on really old phones, scroll just fine, and the same applies to tabs. The slider thing seemed like a very valid concern, but then I googled "range slider" and clicked on the very first link (rangeslider.js.org) and it worked absolutely perfectly on my phone.

There were also two things they said the HTML5 version didn't have at all - a virtual keyboard and clicking on an image. Tapping on images is something people have been doing in HTML for a very, very, very long time. It's not that hard, and it works just fine. I'd say it's probably pretty difficult to mess up.

I think the real advantage shown in the video was the virtual keyboard. I just googled "virtual keyboard" and tapped on the first link on my phone, and the experience was awful.
