I haven't had a plasma display either, but since it's emissive (LCD is transmissive), it can offer much better static contrast ratio, and response time is a non-issue for plasma displays. However, they tend to be 42 inches or larger, which is impractical for most desk setups - you'll probably want to be able to situate it 3-5 feet away. Also, many of them are listed as 600Hz, but that's only internal - they still only take 60Hz signals, so they probably interpolate the extra frames, adding to the input lag.
