HD-SDI output on a macbook pro 17″

3x the functionality in many regards but what it wont do is give you a color critical reference signal to an Apple 23″cinema display … if you have abroadcast HD monitor you ar ecertainly good to go with one of these babies, but if you are looking for lower cost access to a reference signal with existing equipment then the MXO is still playing in a league with little if any competition

Incorrect Gary. The MXO has the ability to do Realtime Downscaling and offers on the fly Letterboxing, Anamorphic and Center cut conversions.
I use that feature all the time with my MXO.
