This is not a bad idea, unfortunately a lot of sites (especially online applications) check for IE specifically and if you don't have it, take you to a message page that says "this page only displays in IE, go away." You see this a lot using Firefox; saavy Firefox users know just to ignore the message because the site works fine anyway. But imagine if your mother in law has just downloaded Microsoft's latest browser, and a site tells her the browser she's using won't work - she'll just get the "deer in the headlights" look and freak out. There really isn't a way out of the corner Microsoft painted itself into on this one.
