I don't disagree with your first paragraph - though I also remember, in London, giant billboards and cinema ads for chrome too as well as advertising for it on the google search page.

However, I switched from Firefox to Chrome when the former changed how DPI were calculated, told everyone that the new way is the right way and it's up to websites to deal with it, and everything looked wrong in the meantime. And then I noticed that on Chrome, not only did things look a bit nicer to me (quite apart from the DPI issue), but the same sites I often used rendered just a little bit faster - faster enough to be noticeable.

At the time, at least for me, Chrome was at least equal to Firefox in terms of product quality.
