Apple is complaining that those Microsoft ads ‘You Find It, You Keep It’ is not nice and according to one Microsoft executive this is a conversation he had with Apple legal:
‘And so we’ve been running these PC value ads. Just giving people saying, hey, what are you looking to spend? “Oh, I’m looking to spend less than $1,000.” Well we’ll give you $1,000. Go in and look and see what you can buy. And they come out and they just show them. Those are completely unscripted commercials.
And you know why I know they’re working? Because two weeks ago we got a call from the Apple legal department saying, hey — this is a true story — saying, “Hey, you need to stop running those ads, we lowered our prices.” They took like $100 off or something. It was the greatest single phone call in the history that I’ve ever taken in business. (Applause.)
I did cartwheels down the hallway. At first I said, “Is this a joke? Who are you?” Not understanding what an opportunity. And so we’re just going to keep running them and running them and running them.’
Here’s Apple’s response to the ads…
And here are the original M$ ads 
I’m all for the campaign, the idea is cool but above all, it works! I agree with the guy who say “Is this a joke? Who are you?” Not understanding what an opportunity!
Microsoft rediscovered compelling advertising.
Of course, they owe Apple for the motivation.
