Microsoft got serious about the browser when they saw the killing Netscape was making with its browser. Once they ran the business part of Netscape into the ground, during the Browser War 1 (BW1), they got incredibly lazy and thought that embedding IE into the OS and other applications would be the panicea for increasing user content and happiness...
Move the clock forward a few years and enter Firefox with a completely open source/revamped of the old netscape product, that's much more secure and less bloated than IE and now they (Microsoft) get serious about browsers again.
Steve, instead a bunch of really flashy crap, how about a product that isn't as vulnerable as what you already have on the table?
If I were a Mac user, I would laugh at the notion of pollution my iMac with any piece/part of IE. Period.
And with the small increases in market share that *nix is making, day by day, he should get down on his hands and knees and thank what ever "God" (presumably the $$$) he prays to, that most people aren't more home/less technically inclined users about *nix.
I chose Paris because even she has the sense to see through his bs
