i work for a large multinational company with 1000's of employes globally, and were looking at installing Samsung LED's in our conferencing rooms, but unfortunately most of our staff are using laptops with VGA D-Sub connections so we are now looking at other makes of TV.
I think Samsung have adopted the new technologies a little bit to quickly and the rest of the world hasn't caught up yet.
But looking at forums there are loads of complaints about connection problems with VGA to laptops, so maybe they just removed the connection to stop people from complaining.
