Well some multimedia plugins will make the page not look right on some other browser such as FF or Opera. Such as flash anims, may be possible to see on yours, but older computers, nope. Another drawback is that consumers hate having to download all these plugins to view certain content.

some thinks like .htaccess drawbacks also..hacking stuff.
