Signals travel much faster and it's easier to use.
You can plug in a USB device, or remove it, without having to reboot your system. There's more good information available at the Intel and MacInTouch USB pages . I've been having a problem using Internet banking because the Web interface was too big to fit on my PC's screen. I was unable to use the virtual keypad for my password as it kept going off the screen. But after I did this the system crashed so I had to reboot and now the screen seems too big and everything on it appears too small.
