This advertisement that is appearing all over the Web is a dual edged sword. On one hand it is trying to encourage users to upgrade from IE7 and IE6 [the latter is particularly backward in features and more security-error prone]. But on the other hand the ad invites jaunty humor like “So far … and the 561 million viruses and spam that got through“. This puts even more emphasis on a)IE9 fully implementing HTML, DOM, CSS and JavaScript standards which all the other major browser vendors currently support and b)getting IE9 out sooner rather than later. Or you could just switch now to Apple Safari5 , Google Chrome, Mozilla Firefox, or Opera Opera 10.5. All can be done in 10 minutes or a lot less at any time.
