We all absolutely do benefit greatly from having multiple competing browsers and render engines - regardless of which one we individually prefer to use.
Therefore I really don't understand the many, many, many "my-browser-is-better-than-yours-you-should-switch" comments in this thread here. Why's everyone trying to convince everyone else that they should use the one and only "best" browser too? What for?
Are people truly that desperate for confirmation and validation, that they need others to agree on their choice of browser?
