Why does everyone make such a big deal about numbering? It doesn't really matter what version they call their browser. It really makes much more sense for them to do their numbering this way. None of the new releases in the past year or two have had any MAJOR changes. All of their changes have been gradual and in steps. This is much better for the consumer as they don't have to spend a ton of time reacquainting themselves with the browser and its features. They only have to spend a minute or two each 6 weeks (if even that).
If they were to call it Chrome version 1.6 then once they get to "1.9" people would be a big change when "2.0" comes out. This probably won't happen. It didn't happen with the change from 9 to 10. Updating the version number with each release really is the most LOGICAL way to do things.
I've been using the Chrome 16-Beta for several weeks now and although it has some major stability issues, I couldn't do without the profiles. I work from home and was tired of having to launch an incognito window for all of my work related accounts...the Profiles are wonderful.
