Tim Bray – HTML5 and the Web:

"HTML-based software has historically provided a better user experience compared to what went before. Everyone in our profession knows that building a good user interface is maddeningly difficult. The discovery, in the early Web browsers, that reasonably-typeset text which embedded simple forms and hyperlinks, and came equipped with a “Back” button, hit the biggest 80/20 point ever in the history of User Interfaces, couldn’t have been predicted by anybody; but it’s as true today as ever."
