I suggested firewire rather than USB as everything I've read says that firewire is better than USB for high speed. And better with longer cables. And there is a 800 Mbps version of firewire, while USB tops out at 480. It should be possible to provide both. Those external boxes for hanging a PATA disk on USB/FW are only about US$10 extra (retail) to have both interfaces (USB2 plus FW-400) rather than just one. So the chips obviously don't cost much. For machines that don't have firewire or USB2 (some machines are USB1 only), there are cards that provide both. (and other combos including Ethernet, SATA ports, ...) I didn't bother to specify gigabit Ethernet, I assumed any new design would not use 100 Mbps, as gigabit is inexpensive now. > What I mean is an external graphic card/accelerator (without add-on > card, so here goes USB2 and Ethernet) and native display connection > (LVDS).
