But you can't convince people to drop Java if they as much have one site/app depending on it. I'd love to install an alternative non-Oracle Java (not because they're significantly more secure, but to diversify the ecosystem a bit, and to stick it to Oracle for bundling that Ask toolbar), but I haven't figured out how to install them in Win7 yet. (that's not for other people btw, but for the computers at the kids centre I teach)
Still, what I wanted to say, the reason I do give them Chrome (or Firefox, or Opera), is because I'm absolutely unfamiliar with IE, no idea how to enable the proper security settings (or if there are any) and I do want to help many people with an AdBlocker (which also can do wonders for one's Internet security, btw).
