that's a good point... I think this is one of the key things Flash had to make its strong start (besides being fast and small) - as a bundle with IE

then again I'm not sure how much freedom MS has this time around (anti-trust lawsuits and I think there may be some more pending settlements) or it would have been done with .NET on Windows already

I could be premature - but I still think Adobe will eventually own web ui in the future... assuming that they eventually get it right on mobile devices
