As far as I hate monopoly and the things that happened years ago with IE6, I'm a bit afraid of what's going on here. I really appreciate the fact that coding a website with webkit bugs in mind will automatically include support of Opera browser now, but does this mean that the whole web will start to code exclusively for webkit engine? This doesn't feel good. I'm afraid webkit will start to dictate features and their bugs-workarounds such as [1] will remain untouched for years.
Besides the fact that I think Firefox is now actually a really great piece of software, this is a primary reason why I continue to use Firefox while everyone else in the office uses chrome.
Yes, you are right, I really love to hear that. But as a webdeveloper my first task after I write some code is to test it in a webkit browser. Webkit is everywhere iPad, iPhone, Chrome, Safari, ( now Opera ). I think bad developers will start to exclude other engines support if percentage of non-webkit browsers goes very low. And since a lot of websites are coded from amateurs ( there's nothing wrong to this ) there will be more and more webkit-optimized content. That's sad!
The "mobile" sites out there are overwhelmingly WebKit-only. We're talking sites from Google, Disney, Apple, various news sites, etc, not sites done by amateurs.
And they're not accidentally WebKit-only in many cases, but deliberately so.
Note that there's some fragmentation in WebKit as well. I think that developers that assume it will make their lives a lot easier will be slightly disappointed in the end.
