Hi, i am using a 23" cinema display as my main screen connected to my mac book pro. It is working fine but i was wondering if i could remove the usb connection leaving only the DVI connection and the Firewire connection. (so i have one more usb port to plug stuff) I know for an ipod both were provided in case you don't have a firewire in your laptop when only 1 is needed. Is it the same? As from bad luck past experience i won't try unless someone tells me it is fine...Thanks!
