Every time the little notification item tells me there's a new version of the Java Runtime Environment available and I install it, I chuckle a little when, as part of th einstallation process, I'm prompted to install the Yahoo toolbar... because one of the features touted on the Yahoo toolbar page of the JRE installation wizard (I think there are only three or so) is “gets rid of annoying advertisements”.
And each time I have to wonder whether it would remove the prompt to install the Yahoo toolbar as part of the JRE installation process, since that feels like an “annoying advertisement” to me.
