tanner have you tried downloadng some of the IE simulators for firefox? I know I have one for my graphic design but I've never tried logging into a site with it, just loading a coded page to see if its hideous or not.

I have tested other MS products. Office 2007 was loads of fun to test out (when it wasn't crashing the computer). I also played with the post-it note one and something else that doesn't come to mind. We have a spare computer that serves as the printer/network hub so we load the betas there and use and abuse it.
