My professional photographer friend will be mightily pissed off by the loss of SD slots. Every dongle is a bit more gear he has to drag around the city while shooting.

My professional radio guy will be mightily pissed off at losing HDMI. Or rather would be, if he were still bound to the Apple ecosystem - he left it several years ago, never to return, because the price/performance ratio on their desktops went down the toilet when they stopped making user-upgradeable "cheesegraters".

Apple has gradually abandoned the Pro market. I thought they were simply trying to move everyone to laptops, but now I can see that they really have no use for non-iDevices.
