Microsoft Is Ready to Kill Internet Explorer

Does anyone care? Will their new Project Spartan convince you to stop using Chrome or Firefox or Opera?

Internet Explorer is still the most popular browser in the world, and will still have to be supported for some time, so why re-brand it? It may not be the choice of the tech-savvy, but it's an immediately recognizable name.

Seems a re-branding is unnecessary to me, what you do guys think?
