For me the beauty of the DisplayPort is that it's very small and offers
multiple connection types via a small adapter (vga, hdmi, dvi).  I've always
hated the huge vga or dvi connectors on laptops.  On my MBP I have one tiny
slot which has numerous possibilities.  If I could upgrade to ThunderBolt I
would but I guess I'll have to wait for a new MBP.
