It's not so much a browser, as a portal to google web services. Google's long term aim is that applications such as word or excel (equivalents) should be online. That said, I just spotted a bug in Chrome, just now, when you type a response into DIYNot that wraps over one line, some of the text disappears until you type another word. But that said, having a brief play around with it, it seems ok, it is said that Javascript runs over 10 times as quickly as on IE8, however I'm always very dubious of these various speed claims.
