The New York Times Service has an article on SVG (SVG: Web Images True to Form Even on the Tiniest Screen, at the IHT), the W3C vector graphics format for which Apple and Kodak seem to have relevant patents. The article presents SVG as a solution for graphics on small devices.
I'm not sure that's so, since images will still be squished into the available space. It's not like SVG magically increases the resolution of a handheld device. The article also claims bitmap images on the web include .bmp files, but that's not an egregious error (especially since they do, because some people don't know any better).
