guys help me choose a cdwriter for a laptop. i have narrowed it down between an acer 24x that has both firewire and usb2 connections and an asus 40x that is usb2 only. my laptop has a firewire port but no usb2. this means that i have to buy a usb2 pcmcia card making the asus a little bit more expensive but still w/in budget. as i understand it usb2 can reach bursts of 480mb while firewire can sustain 400mb. is this correct and will it play a factor considering that the cd writer can not make full use of it? thanks.
