I am curious and a little confused about adding multi monitor support with native screen spanning with macbook pros since the inclusion of thunderbolt. First, I should state that I am looking at purchasing a new MacBook Pro soon as my current model is 4 years old. I remember reading that it may be possible to plug multiple mini display port monitors into thunderbolt peripherals. I currently have a dell 24 and might look to purchase another because Apple displays are not attractive to me. Can anyone offer insight on how to achieve multi monitor support with screen spanning without using something like a matrox usb device?
