I have flash disabled on my primary browser because I have no desire to see flash ads, animations, or the other fluff most people use it for. If I really want to see something with flash, I'll fire up a browser that has it enabled. Now that popup ads are gone w/ mozilla, the most annoying thing on the web is hearing audio when I don't want it, ever.
Vector graphics, on the otherhand, I have no problem with. And if there are features I don't like in SVG, since it is an open standard, someone could write a plugin that allows me to disable those features.
