It seems that the latest Chromium builds are sporting a 2.0 version number (2.0.156.7, to be precise). Surprised? I know I am. The same company that has their most popular service (besides search), Gmail, in beta for over 4 years, releases a browser in September, goes gold in December, and beta releases 2.0 the next month! There are obviously two different philosophies in the Gmail and Chrome departments. So what's different?
