I didn't mean to nitpick. I couldn't tell from the comment if OP was referring to the technical achievements of the Chromium project or was referring to the end-user application (Chrome). The technical achievements don't really matter as much as the value of having whatever 70/80% market share Chrome has. I'm not saying it's not impressive technically, just that they could've skinned Firefox and called it Chrome and put it on their google.com homepage and gotten a (multi)billion users as well in theory. As long as they could use it for the purposes of driving revenue, that would be a win as well, again in theory. Same argument could be made for Android Open Source Project (AOSP) vs Android.
