I thought this was pretty funny, seems Google may need to work on some of their custom error messages.
According to this error I received, Google Chrome is not a supported browser for Google Gmail?
I can not claim to really understand the in depth processing under the hood of Google Chrome, however, I have found it interesting to watch the processes it is doing compared to FireFox.
Using Sysinternals Process Explorer makes it very clear that each tab is using an independent process space while maintaining connectivity to some global files. Hence the way that Chrome has seperate processing for each tab, yet variables are seen across the tabs such as passwords.
Not sure that I agree with Dave Winer that there is nothing new here, some things just might not be as apparent yet.
Google Chrome is a brand new browser, plus I think Google is held to such a higher standard everyone is expecting the most out of the first release on anything they do.
I tend to look for the little things that make up a big win, and there are 2 obvious ones that stand out so far.
