I moved away from Internet Explorer when version 7 was released and started using Firefox. When Chrome was released I installed it just to have a quick look at it’s features, but I have stuck with it ever since. It is fast and very usable, it runs on my Windows and Linux systems, and it syncs all my bookmarks across all my systems. Even though I use Chrome all the time, I always have a copy of Internet Explorer installed on my system because it is still king in the corporate world.
One important note is that Internet Explorer 9 does not run on Windows XP. You need Vista or Windows 7.
