I installed Google Chrome for Linux, the developer build, just to see what it was like.
It's fast; It is extremely fast. I wasn't planning on using it day to day, but I find myself clicking on it more often than Firefox.
The fact that it has no easy ability to block advertisements is pretty much overshadowed by the browser's sheer speed and usability.
And I don't like advertisements. I wonder if this is what Google is banking on.
