Have you tried the new Google Chrome Browser to see how fast it is?
I use Internet Explorer, Firefox, and Chrome all three. It really depends on what I am doing and what features I need. Chrome is my favorite when I need to do research on the web because Chrome is so fast.
If you want to, download the browser here http://www.google.com/chrome/index.html and give it a try. The cost is zero dollars – and that is good. Post your experience as a reply in my blog.
