How many monitors can I run off the new Macbook Pro? The guy at the Apple store said "Yes" when I asked if I could plug in two Thunderbolt Displays, a TV into the HDMI and also use the Retina screen at the same time. I can't imagine he's right but I want to check. He even went further and said you could daisy chain thunderbolt displays. How many displays can you actually run off this thing?
