When I notice flash sites, I notice that they are horribly slow. I don't know if I'm just noticing the bad ones and they're actually in the minority of the sites I visit, or if I'm just visiting the same slow ones all the time, or if flash is just Right Out when you have a dial-up connection, or what. I would not be opposed to it, but I would prefer something that doesn't take significant extra time to use, if possible.
