This would be fantastic if they are able to get the deals.
On my small webapp chrome has already overtaken safari and opera - perhaps in part to the chrome "one tab doesn't crash the rest" system which is pretty handy for webapps.
Good, there is nothing more annoying then having to mangle up HTML for IE, something like this might accelerate the demise.
Too bad they cant just replace all the IE6 out there in one fell swoop.
