Are your parents using Chrome yet? Likely not, but they should be -- it's secure enough for even for them. That said, Chrome is the browser of choice for a good chunk of people -- but it's still limited to "those who know". Know what you ask? Know that Google Chrome is extremely fast, secure, and out of your face.
Where I work, almost every developer uses Chrome -- and I bet if I asked them they would feel dirty after using IE, or even Firefox. I'm also betting that this is a good indication that Chrome is set for a long run of market share increases. Of course, there are probably going to be a percentage of Firefox users (who probably still use Thunderbird for their email) that will never use anything else, and will probably leave some nasty comments on this article.
Over the last year, Google's browser went from 2.4 to 6.7 percent market share according to NetMarketshare. This next year, we should see this rise even faster, if nothing else, because of Google Chrome OS.
Do you use Chrome yet? If not, why not?
