Yep! We have a laptop that gets hooked up to our TV sometimes, for Netflix videos (currently watching the 'Dead Like Me' TV-series), but also because it has a built-in BluRay player. It's great that 1 HDMI cable carries both HDTV and Dolby 5.1 sound.
Our older HDTV (non-Panasonic) only has 1 HDMI input so I had to buy an HDMI switch to switch between the DVR signal and the laptop signal.
