Bloomberg has a reputation all right, when it comes to aapl rumors. However, it certainly isn't a good one.
Really? What rumors did they call wrong vs the ones they got right? Do you have a Tally?
Edit: I should point out that I believe most of their bad reputation came from stating way back in June 2010 that Verizon would get the iPhone in 2011. Everyone called BS. Everyone was wrong. Bloomberg called it.
