I think a "Chrome only" world like the IE-only world we had years ago is a long way away. I don't know how long Chrome has been out, but in that time I have literally never used it. I've never needed to. I could not have made that statement about IE during its heyday. It was nearly impossible to use PCs in any way without using Microsoft. If you never got to experience the Internet in the late nineties, early 2000s, you have no idea how dominant Microsoft was.
