I think its more that laptop manufacturers don't care because no other OEM has made a selling point of it. Its a virtuous circle - some people care about a specific feature, some OEM makes it a selling point, more people start talking about it, OEM B calls an emergency meeting and asks for the feature to be in their new laptop line, they spend advertising $$ promoting it, more people get to know about it and ask for it, more OEMs start including it.
