You mean jacks in the back? Should they be USB jacks?
An HDTV will have dedicated inputs for composite video and audio, S-Video and HDMI. So you can attach various players and cable boxes to the TV.
I'm talking about all sorts of ways to use the TV as a monitor.
For example, I have an inexpensive video camera that comes with cables to hook up to a TV using phono jacks for L&R sound and composite video. SVGA would be another jack to have for hooking up older hardware that may be laying around.

You want HDMI jacks, at least two, better three.
You also want a home theatre controller. This is like a multi input amp, so that all your inputs can go into your sound system. Then you only need one input into the screen - from the controller/amp to the screen.
I’d also recommend a Seagate Home Theater Plus or the equivalent unit fro Western Digital if you don’t have a direct connection to a computer. These inexpensive units let you access content off the web, or from a small portable hard drive, which can store tons of stuff, by the way - movies, TV specials etc.
I would also stay away from power-hungry, heavy, plasma. LCD has improved to the point that it is almost always the best, least expensive choice.
