The support for SVG graphics would designing appealing applications much easier.
While this is generally true, there are two areas which would benefit greatly from SVG graphics.
1.) Nomad mobile applications
Every retina display needs a higher resolution than a regular display. Which means that any Nomad mobile application on a high-end phone or tablet will look less god as on cheap one.
The current solution for printing a company logo is to put a high resolution image on a form and then scale it down. On screen it looks awful but a least while printing it looks ok. With SVG graphics this would not be a problem.
