I actually don't know what's with this browser upgrade but I just felt the need of having one. That's when I tried to use Globe's Chat Assist feature on their website. After I registered to have my on-line account and clicked on the Icon, I was not directed to the application. A window popped up showing that my current Internet explorer 6 is not supported by this net apps.
I am just so glad a friend of mine help me to upgrade my desktop at office. Now I know the difference. I got tabbed window and a browser that's faster than the old version. I guess there's a lot more for me to find out. Perhaps IE 8 has more than this to offer.
