My Cornea CT1702T has S-video, VGA, RCA, DVI, and coaxial inputs
I use the S-video for the PS2, RCA for the gamecube, DVI for the computer, coaxial for cable tv, and VGA occasionally to connect extra computers
The console games look great and so does my desktop. Theres some USB and firewire markings on one of the side panels but no ports so I'm guessing that maybe they'll add it to future models.
Getting a monitor that supports it can be one of your alternatives.
