I thought that chromium itself is the one with none of the google ad/web browsing behavior tracking? I know that SRware iron is as well, but believe chromium is the same...or am I mistaken here?
I've switched to chromium after trying SRware iron, as that one get's updated much faster than iron does.
BTW, is there a noscript avail for chromium/iron?
I don't know about the Win/Mac version of Chromium, but I know the Linux one is still filled with most of Google-ness aside from auto-updating.
As far as I know, there is not a noscript extension out there yet, but any extension that works with Chrome also works with Iron.
