I would never even think about using IE for anything knowing how many threats you face when using it, its not being updated often enough which means no bug fixes or security fixes. Its one of the easiest browser to make keyloggers for, give you trojans often if you visit sites, security is quite low after my standars of using it runs quite slowers than the other browsers i use aswell. And for the guy who said the best were free, the most used browsers are free and i havnt seen any that you have to pay for. You have to test what browser works out for you but i would suggest trying FireFox (2 or 3), Opera or Saffari(it runs for windows aswell). Maybe this is alittle off topic but again i wouldn't think that IE is the best browser for rs in general.
