Are you freaking kidding me?! You're going to call Apple innovative just because they took the Windows 3.1 Program Manager concept of icons in a grid layout and made them look "pretty"? Oh wait, Blackberry had been doing that for years minus the pretty hardware, and everyone from Palm to Microsoft had touchscreens and such long before.
Apple is no different than any other company... they see an idea, they improve on it and claim it new and revolutionary. Every company does this, and every company comes up with some genuinely new ideas too. You don't get to claim one side is true while ignoring all the others.
Anyway, I still think this helps Microsoft in the long run, because I think Apple's "revolutionary" updates are behind them, and I think Google is going to continue to leave it up to the OEMs to defend themselves. That makes Microsoft very appealing, but as others have stated... ONLY if they can really generate some excitement with Windows 8 and Windows Phone 8.
This is Microsoft golden opportunity, and I'm excited to see if they'll take it.
