Yes, rumors are good to keep people "wanting", but I personally miss the days when I was surprised and a "wow" moment when Apple launch a new product.
Like when Jobs introduced the MacBook Air. When he pulled it out of the envelope it was a "What the..!?!" moment that made you run to the Apple store to check it out or buy it. That was a "Wow" moment.
Now..launch day is "just" to see what has been already said.
I don't know why Apple picks and chooses who to go after as far as "leakers", especially Gurman. You would think he is on the payroll and part of marketing.
