this might be accurate for charts or signs, or something where you have letters or icons.
but for pics, best to stay with bitmaps and AA.
having tried vectors myself, I still preffer bitmap images to 'vectorized' images when it comese to textures or backgrounds. it might be faster to render than bitmaps at the distance, but closer they look like anime paintings. you know, step-shaded instead of smooth-shaded.
also, there aren't much programs that work with vector images as raw material. you have to convert them to bitmaps to load them.
