Hearing Macbook Pro Retina is here, I was wondering the idea why Apple a ported HDMI for the new Mac. ? My take on this is, everyone at the keynote was really "up-beat" and thought HDMI Mac was a great idea... However, my take is somewhat different. Previously, Apple have had Thunderbolt, which were already HDMI compatible with an adapter.. Now HDMI is on board, it feeds up carrying an extra adapter in your bag. To make things better (or worse), they also include Thunderbolt, which you you use HMI adapters for anyway. The only exception, and probably the reason Apple decided, is a handful of Thunderbolt compatible devices available. The only reason its not taken of is lack of popularity. Apart from that, Mini-display port on the Macbook Pro Retina, (or just generally) could always be used to HDMI connection with an adapter. So, apart from the above, why include HDMI, *as well* as two Thunderbolt ports ? This would also mean, customers now have a choice, they can either user HDMI directly, or use an HDMI adapter to connect from mini-display port.
