One problem with plasma televisions is that manufacturers started switching to short-decay phosphors a few years ago. While that helps prevent trailing ghosts when you have high-contrast objects moving across the screen, it also makes the low 60Hz refresh much more noticeable. It is like viewing an old SVGA monitor from the early '90s.
In countries with 50Hz mains, you can easily find 100Hz "double scan" models that completely alleviate the issue, running all content at 100Hz. But in North America, the closest we have are some 120Hz 3D models that have the undocumented feature of accepting 1080p120 inputs over HDMI. But as soon as you switch back to the integrated tuner, you're back to 60Hz.
I would love to upgrade my old 42" plasma to a newer, larger plasma screen, but I can't because the glare from the newer screens give me a headache after 20 minutes.
