I preferred multiple browsers. Yes, IE6, but: we hacked, worked around . (heh, saw a site: view in anything but IE). It was a hard issue to manage. I sometimes wondered if fewer engines would bring interop. It hasn't. Google apps are now like OS for OSs Win, Mac, Linux, Android.

Not only that, but a market dominated by fewer engines mean bad behavior is more pronounced, like Chrome ignoring valid autocomplete settings because they don't like devs telling them what to do.
