And the "only" solution is hardly getting them onto a new browser. Moving them to say, Firefox, is only one solution. Another solution would be for MS to produce a standards-compliant browser. IE8 and IE9 are both major steps in this direction. Of course, Chrome itself isn't 100% compliant, and had the advantage of being developed much later in the game, against a well-framed open source stack. And of course, Chrome borrowed all sorts of tricks from IE...
Anyway, there are at least 3 or 4 good solutions for that crowd, only one of which involves Chrome. By the way, I use Chrome and Firefox exclusively. I dislike the piling-on against IE for piling on's sake. To represent IE8 as another IE6 is a little disingenuous, IMO. For what it's worth.
