I don't like those warnings either, but it's quite difficult to test for different browsers on different platforms. I'm glad we own one (ONE!) old iMac. After some hassle we just installed OSX the other week, and now it's sitting in the corner, equipped with VNC and Safari/IE5/Opera so my team can test our sites with it. But not a lot of PC-webmaster have this opportunity.
