A lot of Firefox users who have happened to try IE7 say that IE7 made a lot of changes that imitate Firefox. The icons, for one. I got to look at some screenshots and I must agree the icons look like those in Firefox, so much different than the layout and icons that I see this moment in IE6.

Chroder, does IE7 slow down your father's computer or browsing? Someone said it slowed his computer, so I am thinking twice of the upgrade. The enhanced security might convince me, though.
