There were several people showing off the latest S60 browser software (built on WebKit) running on Nokia phones.
There is richer Ajax support, and was even a nudge, nudge, wink wink comment regarding support of canvas and the like.
Still, although it is great to have Safari on the phone, and zooming around the page is fun, there are still huge issues around screen size. In a world where we see more 30″ monitors, or duals, remembering the little guys can get hard. Ajax brings challenges such as changing multiple areas of the screen at the same time.
Has anyone had particularly good experiences with Ajax on the phone? Maybe someone living in a country where you actually have decent service? :)
