I don't like it at all, I find it hard to find tools that were obvious in IE8, there is a little box that keeps leaping up when you are here in AB - the general opinion of some of the others on here with IE9 has been that they don't like it either. We are thinking of going back to 8.
Boxtops ,have d/loaded the Google toolbar and found all the add ons I need ,ie google earth,add on buttons.bookmarks,autofill. Must admit took a while searching.
I don't know anyone that works in the industry that uses IE, although it has been getting better since IE6 (it couldn't have got a lot worse!) it's still trailing far behind the other offerings (firefox, chrome or even opera)
I have had no trouble with IE since IE6.I tried Firefox at that time and got fed up with the sites it didn't work on properly so went back to explorer when IE7 came out.
