The one thing I have always liked about IE that Netscape has never supported is browsing in "fullscreen" mode. No wasted space, no chrome fluff - just the facts, ma'am. Also great for my laptop, with it's 800x600 display.
Yeah, I love F11. Full screen anything is AWESOME (even if it doesn't, for some strange reason, utilize my Voodoo's 3d acceleration). Especially full screen HTML-Kit.
