Why would anyone need this is a laptop? Seriously, what is the use-case for this? When I'm on the road I would really appreciate a built in 3G modem or a second battery e.g. instead of the (useless) optical drive.
As for the mini display port: I never figured out what the benefits should be. Every meeting room I went so far, has a projector with a VGA input. As a user, I have to always carry an (overpriced) adapter. What for?
I think, Apple doesn't understand the difference between a laptop and a desktop.
seriously? All these years people ask for all these ridiculous things in apple products and apple always says its impractical why would you need that. now they pioneer something and do it first and of course apple users are so trained by now first thing they say is "why would I need this?" lol.
