He probably loves itunes for what it accomplished. Remember the music industry before itunes? The way in which it made a lot of things possible and easier?
And the whole app store mechanism? Whether it is itunes or android's or whatever's?
That's what he loves it for. (And I'm assuming you're wondering why he loves a product that is so ugly/slow/complicated/whatever; I suspect that's not Steve Wozniak's point).
