I took my wife and I FOREVER to find a motorized baby swing that didn't take a buttload of C or D batteries, just plugged into the wall. Wires are highly underrated.

OTOH, we just recently moved the computer to the TV's spot, bought a tuner card, a big ass monitor (set to a hilariously low resolution) and a wireless keyboard/mouse (combined, not separate.) It's a pretty sweet setup. Pause tv, check facebook, look for something on Netflix, check hulu. Highly recommended.
