im gonna stick to the fox for a while. the amount of information google is gaining between searches, gmail, and now chrome.  I am afraid skynet is upon us. Judgement day is coming, and google be thy name.
Seriously though, I am impressed with chrome, as soon as enough add ons become popular I may switch.  I play around on opera and chrome all the time.  Fun at home test, close chrome close firefox, get out stop watch,  and open tab 50 of your favorite sites in each repectively.  so far FF has one 3 times, Chrome 2times.
