For those of you who think HDMI is the stuff... you probably still have VHS and Beta players in your home.
HDMI has a resolution capability of 1080 while mini display port has a resolution capability of 2560x1600. If Apple were to implement HDMI in their devices, they would render their own 30" Cinema Display useless since it has higher resolution than 1080. Not to mention the royalty free design on MDP.
Your statements are just as uneducated as they're arrogant.
HDMI 1.3, which is the most common one, supports 2560x1600. HDMI 1.4 supports 4096x2160.
