I have Toshiba 32WLT68 which has 3 HDMI inputs which I think should suffice for foreseeable future. Sky HD, upscaling DVD and, when I get hold of one, a PS3 will fill that amply. PC is via VGA and that leaves a component input for probably a Wii when I can be bothered. Therefore, anymore than 3 HDMI inputs is overkill in my opinion.
