I use for preference Google Chrome, but when we bought our GPS from Costco last week, when we did the downloading and formatting, they told us to use Internet Explorer cos that's what they use and couldn't give us directions via Google Chrome.
I like Chrome because the Home Page comes up with everything I regularly use, Yahoo, Gmail, Google Explorer, Youtube and so forth, right there on one page. And for information, nothing beats Google. I don't think I've ever had a search where I haven't found what I was looking for, answer-wise. Come to think of it, 90% of the Best Answer points I get are by using Google and Wikipedia and that's close to 40,000 points in three years since playing with yahoo q's and a's. I signed up in 2006 but never used it until 2009, so 3 years using is all.
