Hi guys! I am planning to use a monitor that I have as a THIRD display! But, as we know, in macbooks we cant use more than one external display WITHOUT spending some money (more than 200, I'd say). But, nowadays, we can use a USB port to do that! its a USB to VGA adapter! And here is my question: which one is the best for my macbook pro 15.4" mid 2010? I found this website: http://www.displaylink.com/shop/index.php?product=5 I dont know if this is the best manufacter, but I only know this one... Thanks a lot!
