Plus, vector graphics compress *much better* than raster, but they are *much slower* presenting them. Try filling a web page of svg flags, and see how much it takes to load. Or compare times showing times for raster and vectorial.
Exactly this I do often: Displaying the 208+30 national flags all as SVG on one browser-page! :-) It takes about hmm ... about 62 seconds. I just made a first time time-measurement. My hardware uses an Athlon-Thunderbird 2 GHz with 4 GB RAM running FireFox 3.6.17.
