So it has everything you'd expect from a browser-based operating system and gets right to the heart of the problems. By making the browser more stable and more usable for long periods of time, they've created something very, very interesting, and something that should be a huge win for RIA developers everywhere - even Flash or Silverlight developers. So the easy answer is "Windows Killer". But I didn't see anything in the comic about device drivers. I didn't see anything about hardware acceleration. In an extra bit of irony the beta is only available on Windows. So who's in trouble? Firefox, even if they don't acknowledge it.
Firefox has become synonymous with memory leaks and an antiquated code base. Despite a very good, lucrative arrangement for both sides, Google started from scratch and used WebKit as the HTML renderer. Firefox's market share is still somewhere in the 25% range, while IE controls the bulk of the rest. So while it's making inroads, it still appeals most to the hard-core geek crowd. And add-is are a major selling point over Safari right now. With Google Chrome you get the WebKit engine, you get add-ins, and you get a ton of more useful features in your browser. That same crowd that flocked to Firefox is going to embrace Google Chrome with open arms. The crowd of folks who just use whatever comes with their operating system? Not so much. Google will make more inroads than Firefox can, but it's still going to take a ton of market-share from everyone's feel-good open source browser.
I'm very, very excited about Google Chrome. This is a big day for RIA developers because Google started from scratch. They're building a train that will actually be able to run on the high speed tracks of the internet. We've been pushing and pushing and pushing for a long time, but the browsers just haven't been able to keep up with demands. Google Chrome should be a big leap forward.
