Apu, While the title of the article does mention fast downloads ("Smart Curves. SVG promises fast downloads and new design flexibility for the Web), the article does attempt to keep expectations at least somewhat in line. Here is a snippet of text from that article: "Vectors aren't for everyone With all these cool features, why would anyone want to use anything but SVG? Unfortunately, while you can draw a lot of things with vectors, there are some things vectors are just lousy at. Most importantly, scanned images (which are always bitmapped) will generally beat vector art in detail and photorealistic quality. The more detail in an image, the less useful vector art is. (Drawing every leaf of every tree is a forest using Bezier curves would be painful). Fortunately, SVG lets you mix images in formats such as GIF, JPEG and PNG with your vector art.... Of course, the vector art could be scaled to any size (or rotated or skewed or whatever) and remain high quality, whereas the bitmapped image may become blurred -- an effect similar to what happens when you make dramatic size changes to an image in Photoshop. Well, no one said there wouldn't be trade-offs." Another aspect that no one has mentioned yet is progressive rendering. Even if a given SVG file turns out to be the same size as a GIF, and even suppose you don't care about zooming, or printing, or interactivity, or animation, or text selection, or accessibility, SVG has the advantage that it can start rendering meaningful graphics as it receives it (and a user can start interacting with it immediately), whereas an image generally is indecipherable until fully loaded, even if interlacing is used.
