"The more open platform won?" Really?!
Certainly not for all values of "winning." Not even for the most obvious ones.
Since your analysis seems to be lacking an actual connection with the facts, I'm guessing you would be surprised to learn that, using Reported Income as the most telling metric of success, Apple is blowing MS away.
For example, http://www.asymco.com/2011/09/29/comparing-revenues-apple-and-microsoft/ provides the following tidbits:
-- The Mac business generates more Revenue than Windows
-- iOS powered devices generate more revenue than all of Microsoft’s products put together
-- Apple’s revenues grew 413% since Q2 2007 while Microsoft’s grew 26%
So it seems if Apple is to be, as you claim, "a fading memory," it may be due to some diminishing capacity on your part, and not a true measure of Apple's continued success.
