I'm baffled by why MS still cares about their browser. It made sense in the IE 5/6 days when they were using it as a way to lock people into their platform, but that seems unlikely to happen again unless their browser offers some huge advantage (ActiveX support was arguably the advantage in the past). This seems especially unlikely given that they are irrelevant in the mobile space.

Pushing Bing search as a replacement for Google search seems like a much smarter play with a much larger upside.
