    3's the best and most current and has speeds comparable to PCI express. Insane fast...So basically makes all the other video ports worthless.

    usb 3 is the best and newest UNIVERSAL SERIAL BUS ie USB not video port it is better described as an I/O port( in/out ).As well as the signal stream speed of older USB the current it can deliver to power a usb device is different .1.0 and 1.1 can deliver about 100m/a and usb 2 can deliver 500m/a.If you are considering something for commercial availability , then look at usb 2 as that is well established and readily available for use on billions of computers ,however usb3 is the new kid on the block and a limited market .

    Yess Chrissy but USB3 is now faster then Firewire. So what happens when your video ports are slower then your USB? You use the USB as your video port. :)
