Windows Mobile may have been there before iOS but it came after Blackberry and palm. iOS and iPhone was also revolutionary. Smartphones changed substantially from that.
Internet Explorer wasn't the first browser on the market but by the time Chrome had come around Microsoft had let it languish and it became pretty awful. For a long time Microsoft had convincingly won the browser war.
Same with MSN messenger, it didn't keep up. And nobody has ever decisively won that chat app war anyways .
Smartwatches have been around for a very very long time. What Apple did was get smartphone integration right.
Zune Pass isn't a streaming service, its a DRM laden online music store. So more akin to iTunes than Spotify or Apple Music. And it was very late to the game.
