The latest Samsung firmware at the time of testing (1056) had a few bugs with this TV:
Multiple times during testing the TV would freeze for ~3 seconds, and wouldn't respond to any remote inputs.
In the Movie picture mode, our 20% gray response time square would turn orange when set fullscreen, but when the TV's home menu was opened it went back to gray. To avoid this issue we tested response time in Standard mode rather than Movie.
Hopefully these issues are fixed in a future firmware update.
