This list boils down to: 1. Heavy-duty graphics, including video (canvas/svg) 2. Collaborative text editing (canvas/svg/ajax) 3. Read books in a mobile browser without a connection (localstorage) I kind of expected a little more variety. Off the top of my head, here's what I didn't expect HTML/JS to do, in addition to the above: 4. Work on almost all new phones, without converting to a special language (Remember WAP/WML)? 5. Have open & standardized libraries that anyone can use to make coding easier (proto/moo/jQ). 6. Enable anyone to write browser-plugins easily. 7. Run as a server (node.js) 8. Constantly improve in performance 9. Be written using templating systems: SaSS, HAML 10. Still be handwritten in 2010 and beyond.
