Here is a story from Google, on why the world needs another browser ?. I am not convinced nor are several other users like me , who find no reason convincing enough to dump Firefox. I did a few comparisons on loading / rendering times of a few web sites and sure chrome is just a little faster but not noticably to millions of average users. Apart from that I also found chrome to break at few sites which IE / FF rendered fine.  The only thing for now chrome introduces, is the pain in the *!@  for developers who have to fix issues on chrome for apps they have already developed.
