I mostly use IE and do not have a problem with it. I got tired of downloading pop-up blockers, though, so I got Mozilla for my ONE site that has too many pop-ups and spyware on it. Otherwise, I can't stand the loading time for that browser and I feel the IE interface is easier on the eyes. I also can't stand tabbed browsing. I use it once in a blue moon for like two seconds, then it's over.
Perhaps the people whose IE keeps crashing do not have enough memory. I upgraded my seven year old computer to 128 MB of RAM (haha... note that this is only for home use, no gaming, etc), and the computer works like a dream, and I can't remember the last time IE just randomly crashed on me.
