Also, I often can't watch video content without unplugging my speakers and putting my headphones in so I don't disturb other people. Oh, and my laptop fan starts going like crazy and my CPU goes to 100% with FLV.
There is a pet peeve of mine, I usually have my monitors speakers plugged in and active, so if I land on a page that starts playing some silly video I run the risk of waking up the whole house. Ads with video in them are even worse, a surefire way to let me never ever visit that site again (these warrant an entry in my hosts file).
Video is an effective way to warm the planet, burn nonrenewable fuels, and send more batteries to toxic dump sites.
